Rubber keypad is one of many electronic keypads. Its main function is to achieve conductive keys through conductive glue. When the conductive rubber keypad is pressed down, the conductive rubber of the key can be electrically connected with the contact below. When the silicon rubber button is released, the conductive rubber under the button springs up and will not communicate with the connection below.

The conductive material of the rubber keypad is a black conductive adhesive. When this conductive adhesive is added with a conductive filler, the conductive effect can be achieved.

Conductive rubber buttons need to consider the diameter, length, width and height of the rubber overlay, button scheduling, pressing force requirements, product hardness, color, conductivity and other requirements.
