Practical articles on designing, sourcing and manufacturing custom membrane switches, graphic overlays, silicone keypads and HMI assemblies — written by the engineers on our production floor in Shenzhen.
"Membrane switches and mechanical keypads both survive millions of actuations, but they suit very different products. Compare cost, sealing, backlighting and reliability to pick the right interface."
"Polyester (PET) and polycarbonate (PC) are the two dominant graphic overlay materials. Learn how chemical resistance, printing, flexibility and cost decide which one your membrane switch needs."
"Before you approve a membrane switch drawing, you need to check these seven specifications — from actuation force to tail routing. A 10-minute review now prevents expensive tooling changes later."
"Silicone rubber keypads combine molded key travel with sealing and durability. This guide covers key force, dome design, carbon pills, colors and the tolerances that make a keypad feel right."
"LED backlighting, electroluminescent (EL) lamps and light guides each have different brightness, thickness, life and power characteristics. Here is how we choose the right one for a membrane switch."
