Silicone rubber single button/ mechanical push button

A mechanical push button made from silicone rubber provides one flexible control surface within a matching assembly. Custom size, color and hardness options allow the button to suit the housing and desired feel. The molded key must remain properly supported when pressed away from its center.

Check the clearance around the visible face and the alignment with the mechanism beneath it. An off-center press can tilt the key, bringing one wall closer to the panel opening. The rubber should still return naturally without a rim dragging against the enclosure.

Custom engraved or embossed identification should fit the key face without creating an awkward pressure point. Evaluate the button after the housing is secured, since the retained perimeter can be compressed differently than on a loose sample. During assembly, keep the locating region seated and the underside clear of debris. If response changes after maintenance, restore the intended support and orientation before modifying the molded part. A single key can look symmetrical externally while its underside determines how it must sit against the internal mechanism.
