Pushbutton switch actuating device

摘要

The switch operating device has a rubber mat (15) inserted between the switch pushbutton (11) and the switch (12), with a necked section (18) of the pushbutton fitting through a corresponding hole in the rubber mat, for supporting the switch. The bottom end of the switch pushbutton projecting from the underneath of the rubber mat may have a conical shape (20), with the rubber mat acting as a return spring for the pushbutton.
