Manufacturing & quality

Confidence comes from specifics.

A switch is only the right switch when its function, fit and supporting documentation match your application.

Manufacturing background

Design. Production.
Technical confirmation.

The 2023 company introduction describes an integrated design, production and sales operation, with its own testing laboratory.

The catalogue provides a useful view of the product range and historical documentation. It does not replace a current factory capability review, model-specific approval check or sample evaluation.

For a sourcing decision, request current production information and the evidence relevant to your selected component.

Request current capability information

A buyer’s technical checklist

From requirement
to a verified specification.

01

Define the application

Tool type, operating function, supply, load and destination market establish the requirements.

02

Confirm the interface

Compare the housing, actuator, mounting, terminals and wiring with the actual assembly.

03

Request the evidence

Check the current drawing, rating sheet and applicable certificate against the exact part number.

04

Validate before volume

Agree the sample evaluation and acceptance criteria before committing to production quantities.

Recommended sourcing checkpoints, not a claim that a specific production or inspection process has already been verified.

Documentation, with context

Look beyond
the certificate logo.

Ask for evidence that applies to the exact switch you are buying.

The 2023 catalogue displays CQC, TÜV and KC-related documents, along with quality-management and patent materials. These are historical catalogue references, not confirmation of current validity or coverage for every product.

  • Certificate number and issuing body
  • Named manufacturer and covered model
  • Applicable standard and electrical rating
  • Current status and document revision

What this website does not claim

We do not publish unverified production capacity, customer logos, factory photographs, delivery promises or blanket “certified” badges. Current evidence should be requested as part of your technical and commercial evaluation.
