Silicone Rubber Keypads
Molded silicone keypads with tuned actuation force, custom legends, multi-color keys and conductive pills. From remote controls to medical handhelds, we tool, mold and test keypads that survive heat, cold, moisture and heavy use.
A silicone keypad is a single molded rubber mat carrying every key. Each key dome returns to its original shape after pressing, so the whole assembly needs no springs — and the rubber seals the electronics beneath.
Under each key, a conductive pill sits on the underside of the dome. Pressing the key pushes the pill onto a PCB contact pad or membrane circuit, closing the switch. Release and the silicone's natural elasticity snaps the key back.
Hardness 30–80 Shore A and force 80–350 g, tuned to your application and user feedback.
Laser engraving, pad printing or two-shot molded legends that never wear off.
Carbon, silver or gold pills matched to your PCB or membrane circuit contact.
Square, round, elliptical, stepped, crowned or custom-drawn key geometries.
Translucent silicone for uniform LED backlight, plus separate light pipes and rings.
Conductive rubber keypads for EMI shielding in noise-sensitive electronics.
Matte, glossy or fine-grain key tops with anti-slip and anti-fingerprint finishes.
Adhesive backing, bezel mounting or PCB-mounted with alignment posts.
