Silicone keypad rubber push button electronic equipment

A Silicone keypad rubber push button should line up with the enclosure opening and the underlying actuation point. Its molded flexibility provides movement, while the surrounding support and clearances determine how that movement is used by the complete control.

ETOL offers custom dimensions, hardness, colors and molded identification. Define the key's resting position and operating travel before finalizing the profile. A raised top or logo should leave enough room for the key to move without rubbing the panel.

During assembly, keep the connecting rubber regions relaxed and inspect beneath the key for trapped material. Secure the housing gradually and evaluate response with the intended switch or contact circuit. Check return after a slow release as well as a quick press. During service, protect the underside from contamination and inspect the flexible junction for damage. If the key remains depressed after closure, correct its locating position or internal spacing instead of relying on repeated pressing to free a portion held against the enclosure.
