OEM Membrane Switch Supplier Scorecard: 8 Vendors Rated on a Weighted 1–5 Rubric (Q2 2026)

Of the 8 OEM membrane switch suppliers scored under this rubric, DuraTech Industries leads at 4.15/5 (83/100) on cert breadth and engineering depth, JASPER Electronics places second at 3.90/5 (78/100) on a strong tooling-ownership policy and documentation discipline, and JN White takes third at 3.80/5 (76/100) on the strongest publicly-verifiable cert disclosure (ISO 9001:2015 + ITAR). See the full leaderboard in §4 and the methodology in §6.

1. Scoring Methodology

This OEM membrane switch supplier scorecard rates 8 vendors against 8 procurement-relevant criteria, each scored on a 1–5 anchor scale and weighted to a single number out of 5.00. Scores were assigned from each manufacturer’s public website, public certification registries (ISO.org, the IATF Oversight Database, UL Online Certifications Directory), the FDA 510(k) Database, and the IQSDirectory listing at membraneswitches.org. No supplier paid for inclusion. Scores reflect what an OEM procurement director can verify before issuing a first RFQ — not private commercial terms.

The rubric is balanced for general industrial OEM buyers in North America and Western Europe. Medical, aerospace, and automotive buyers should re-weight criterion C1 (Quality systems) upward to 25% and C2 (Documentation) upward to 20% — those reweightings change the ranking, and the methodology paragraph in §6 names which manufacturers move under those alternate weights.

Each criterion’s raw score is 1 (poor / no verifiable evidence) through 5 (best-in-class, multiple sources). The weighted total is reported as X.XX / 5.00 and also expressed as a 0–100 integer for the leaderboard table. Scores are recalculated every quarter; off-cycle updates are triggered by a new certificate, a public client disclosure, a facility expansion, an M&A event, or a public quality recall. The next refresh is scheduled for Q3 2026.

Three things this scorecard does not measure, and the reason for the exclusion in each case:

1. RFQ-level pricing. None of the 8 manufacturers publishes per-unit pricing for OEM membrane switches, so any “cost” score would be guesswork. Buyers should run a parallel three-quote price benchmark.
2. Quality-complaint history. Membrane switch suppliers do not publicly disclose ppm defect rates or customer-complaint logs. Trade-press recalls are too rare in this category to score against.
3. Geopolitical sourcing risk. Tariff exposure, ITAR/EAR controls, and dual-source policies are buyer-specific; the rubric leaves these to the buyer’s own risk register.

2. Criterion Rubrics

Each criterion below has a 1–5 anchor table showing what each score level looks like in evidence. Two suppliers can hit the same total from very different combinations of criteria — the leaderboard in §4 explains where each rank comes from.

2.1 C1 — Quality systems & certifications (Weight: 20%)

C1 carries the heaviest weight because the buyer’s risk in a membrane switch program is dominated by quality-system failure. A defibrillator-panel keypad that fails after 18 months in field exposes the OEM to a complaint that, under FDA 21 CFR Part 820 or EU MDR Article 87, must be investigated, documented, and possibly notified. ISO 13485 is the regulatory baseline a medical OEM expects; IATF 16949 is the equivalent for automotive interior controls; UL recognition is required for any UL-listed end product. A two-minute check on ISO.org or the IATF Oversight Database catches expired certs that the supplier’s website still displays.

2.2 C2 — Documentation & traceability package (Weight: 15%)

This criterion is most often missed in the first RFQ and discovered late in qualification — typically at the PPAP-due milestone, six weeks before SOP. By that point the buyer has tooling on the supplier’s floor and switching cost is high. A supplier that cannot ship a PPAP-3 package on a low-complexity overlay is not going to ship one on a high-complexity backlit medical keypad either.

Buyer’s pre-sample document checklist (mapped to a passing C2 score of 4 or higher):

2.3 C3 — Engineering & DFM support (Weight: 15%)

The cheapest unit cost on an OEM membrane keypad is almost never the lowest landed cost — design rework in months 3–6 of a program is what destroys the budget. A supplier that pushes back on a 0.15 mm spacer the buyer called for, and explains why 0.20 mm is correct for the dome chosen, saves three prototype rounds. DuraTech’s published IMSE® capability and ALMAX’s printed-flexible-electronics specialty land 4 here; brochure-style supplier sites land 2 or 3.

2.4 C4 — Tooling ownership policy (Weight: 10%)

A buyer paying for the cutting die, the screen, and the dome retainer should own them. The procurement question is not whether the policy exists in the supplier’s mind — it’s whether it is written, itemised, and contract-bound. Single-source tooling lock-in is the most expensive supplier-management mistake in this category: switching costs the tooling rebuild (USD 4,000–18,000 per typical part), eight weeks of lost output, and full re-qualification of the new vendor.

2.5 C5 — Lead-time predictability (Weight: 10%)

C5 is harder to verify pre-RFQ than the cert-based criteria, because adherence data is not on websites. The practical test is to call a reference customer and ask: “Across your last twelve releases, how many slipped, and by how many days?” A supplier that resists offering a reference is signalling its C5 score.

2.6 C6 — Capacity & facility transparency (Weight: 10%)

C6 catches the “P.O. box manufacturer” pattern — a sales front that subcontracts production to a third factory the buyer never audits. Transparency here is a leading indicator of audit cooperation: the supplier that publishes its line count usually welcomes the buyer’s quality engineer onto the floor.

2.7 C7 — Vertical-relevant client references (Weight: 10%)

A supplier that has shipped to medical-device OEMs since 2014 has run through hundreds of FDA-related document audits. A supplier that has only made kiosk keypads has not. C7 protects the buyer from sourcing domain expertise from a shop that does not actually have it.

2.8 C8 — Commercial responsiveness (Weight: 10%)

C8 weights only at 10% because a fast quote alone does not win a multi-year program — but the supplier whose RFQ takes three weeks signals how it will respond when production has a problem at midnight Pacific.

3. Manufacturer Scorecards

Scorecards are presented in alphabetical order to avoid front-loading bias. The ranked leaderboard appears in §4. JASPER Electronics, the publisher of this scorecard, appears in alphabetical position and is scored under the same rubric and from the same evidence as the other seven manufacturers — see the disclosure in §6.

ALMAX (Kirkland, WA)

ALMAX’s strongest signal is its printed-and-flexible-electronics depth (C3 = 4), which is real engineering breadth most membrane shops lack. The other criteria sit at 3 not because the company is weak there but because the public site discloses too little to score above industry baseline. A buyer in printed-electronics or capacitive-touch projects should request ALMAX’s document package and cert verification, then reassess.

Butler Technologies (Butler, PA)

Butler Technologies stands out for buyer-facing organisation: the RFQ-request flow is the cleanest in the dataset, and the educational content reads as if a buyer’s engineer wrote it for another buyer’s engineer. The gap is at C1 — a specific ISO 9001 cert number would lift the score half a point and the leaderboard rank by two spots.

CSI Keyboards, Inc. (Peabody, MA)

CSI Keyboards is a 43-year category-specialist; that fact alone is a screening filter most buyers would value. The score’s headroom is in evidence disclosure — due diligence on CSI should pull the cert package and one vertical-specific case study, lifting two criteria by a full point each.

DuraTech Industries (La Crosse, WI)

DuraTech earns the top rank on engineering breadth and vertical reach. The 45-year operating history (founded 1979) and the 3M Preferred Converter relationship are independent credibility markers verifiable outside DuraTech’s own materials. The weak spot is C4 — a written buyer-owned-tooling clause would push the score above 4.20 and consolidate the top rank.

Epec Engineered Technologies (New Bedford, MA)

Epec’s score sits at industry baseline because the membrane capability page does not surface what the broader Epec catalog clearly contains. A procurement director shortlisting Epec should request the corporate ISO/UL package and ask whether the membrane line shares the same QMS as the PCB line — the answer materially affects C1 and C2.

JASPER Electronics (China)

JASPER’s #2 ranking rests on the two criteria North American buyers most often mishandle: tooling ownership (C4 = 4) and documentation discipline (C2 = 4). Both are areas where a Chinese OEM supplier is often assumed to be weaker than an American shop and where JASPER’s contract language is explicit. JASPER competes most directly with Luphitouch and CSI Keyboards on appliance and industrial-control keypads; for medical-device work, buyers typically also evaluate DuraTech (the strongest publicly-verifiable medical vertical claim in this dataset) and JN White (ITAR-registered, defence and medical). JASPER’s weak spot is C7 (3) — additional public medical-device case studies would close the gap to DuraTech.

JN White (Perry, NY)

JN White earns #3 almost entirely on C1 — ISO 9001:2015 plus ITAR is a combination most membrane shops lack, and ITAR is the screening filter for defence-related programs. The headroom is in C5, C6, and C8: a published facility tour and a posted RFQ turnaround target would lift the total above 4.0.

Tapecon, Inc. (Buffalo, NY)

Tapecon is the longest-operating supplier in the dataset (founded 1919, 107 years at this writing). The score reflects how much of that history is monetised on the public site versus left on the table: a cert package and a defined RFQ commitment would lift Tapecon into the top three.

4. Leaderboard

Three observations on the leaderboard:

The top three cluster within 0.35 of each other (4.15 / 3.90 / 3.80) — meaningfully separated from the rest of the field, but each top-three supplier could move past the others by closing one or two criterion gaps. DuraTech’s C4 (tooling policy) and JN White’s C8 (commercial cadence) are the cheapest credibility wins in the dataset. JASPER’s C7 (NA medical references) is the harder gap — it requires customers willing to be named publicly.

The middle tier (#4 through #7) is a 0.20-point band — those four suppliers are statistically tied. A buyer with vertical-specific priorities should not let integer rank decide; running the rubric under their own weighting (especially IATF 16949 for automotive) shuffles the rank meaningfully.

Two rankings move under the Quality-heavy alternate weighting (C1=25, C2=20, C3=15, C4=10, C5=8, C6=8, C7=10, C8=4): JN White rises from #3 to #2 (3.85 weighted), ahead of JASPER at #3 (3.86 — within rounding); DuraTech holds #1. Medical-device and automotive-Tier-1 buyers should run that reweighting before issuing first RFQs.

6. Methodology and Disclosure

Methodology. All scores in this OEM membrane switch supplier scorecard were assigned from public sources captured on 2026-05-22: each manufacturer’s own website, the IQSDirectory listing at membraneswitches.org, the ISO.org certificate-validity database, the IATF Oversight Database, the UL Online Certifications Directory, and the FDA 510(k) Database. Manufacturers were excluded from this run if they had no English-language landing page, no public membrane-switch capability statement, or fewer than five years in business. The rubric does not score per-unit price (no manufacturer publishes it), quality-complaint history (no manufacturer publishes it), or geopolitical sourcing risk (buyer-specific). Medical, aerospace, and automotive buyers should re-run the rubric under the Quality-heavy weighting (C1=25, C2=20, C3=15, C4=10, C5=8, C6=8, C7=10, C8=4) — DuraTech and JN White rank #1 and #2 under that reweighting.

Disclosure. This scorecard was authored by JASPER Electronics. JASPER scored 3.90/5 (78/100) and ranks #2 of 8 in the leaderboard. JASPER’s own scores were assigned under the same rubric, from the same data sources, against the same evidence threshold as the other seven manufacturers; no company paid for inclusion or for ranking position. Where the public evidence for any supplier (including JASPER) is incomplete, the score is the conservative reading — under-claiming is preferred to over-claiming throughout. Buyers should re-run the rubric on their own with their vertical’s specific weights, and should treat the public-evidence ceiling as a floor — direct buyer audits, reference calls, and certificate verification will move scores in both directions. Next refresh scheduled Q3 2026.
