Custom high quality rubber silicone keypads for electronic equipment

Rubber silicone keypads are custom molded around the physical controls of electronic equipment. Their shape should correspond to the enclosure openings and internal switch locations, with enough support to hold the sheet in position. The way the equipment is assembled and later serviced influences which locating features are useful.

Review the sequence in which the keypad, circuit, and housing meet. A sheet that stays in place on an open bench may shift when the enclosure is turned over or closed. The design should establish the intended position without stretching the keypad across mismatched features. Check the completed group of keys after fastening, especially those furthest from the main locating point.

Different shapes and material choices are available for customization. During service, keep the sheet oriented correctly and prevent particles from remaining beneath it. Free return should be checked across the layout before the equipment is put back into use. A key that catches after reassembly may reflect changed seating rather than wear of the rubber itself.
