Frequently Asked Questions

What is a membrane switch?

A membrane switch is a user interface device that uses pressure to open and close circuits. It consists of layers including graphic overlays, spacer layers, and circuit layers, commonly used in industrial, medical, and consumer electronics.

What’s the difference between tactile and flat membrane switches?

Tactile switches use metal domes to provide physical feedback when pressed, while flat membrane switches are non-tactile and rely on visual or system feedback. Tactile versions are preferred for applications requiring user confirmation.

Can you customize the design and size?

Yes, we offer full customization including size, shape, color, backlighting, connectors, and circuit layout. Our in-house design team works with your specifications for OEM/ODM projects.

What certifications do you have?

We are ISO9001:2015 certified and comply with RoHS standards. Our production follows strict quality control procedures with in-house testing capabilities.

What is the lead time for samples and mass production?

Sample lead time is typically 7–10 working days. Mass production lead time varies based on order size and complexity, usually 15–25 days after sample approval.
