Conductive Silicone Rubber Keypad with Membrane Switch

A conductive silicone Rubber Keypad with Membrane Switch needs the molded key movement to correspond with the switch layer beneath it. Their locating features and assembled spacing should allow the intended input without a layer being held down by the surrounding housing.

ETOL offers custom sizes, hardness, colors and molded identification. Establish the panel opening, keypad resting position and switch support as one stack. A change in one layer can affect actuation even if the outer key shape remains the same.

Assemble the parts without stretching or creasing their flexible regions. Inspect alignment before closure, then check the completed electrical response with the housing secured. Press from the intended direction and verify return after both slow and quick release. During service, keep the contact area clean and support the membrane appropriately while separating components. If response changes after reassembly, inspect the layer seating and board or switch support before modifying the key. Replace damaged webs or switch-layer components through the intended process rather than adding improvised material to bridge an uncertain contact.
