A switch assembly is provided to actuate a pair of switches using a single key cap, e.g. for a camera that utilizes a first switch to activate an image focusing function and a second switch to activate a camera shutter. The switch assembly comprises an inner switch and an outer switch, wherein the outer switch partially or completely surrounds the perimeter of the inner switch. The outer switch comprises an upper conductive surface and a lower conductive surface that, when in contact, electrically couples two terminals for closing a circuit. The inner switch comprises an actuator and a dome switch. When the key cap receives a first downward force, only the outer switch becomes activated and a first electric circuit is completed. When the key cap receives a second downward force that is greater than the first force, the dome switch collapses and a second electric circuit is completed.
A switch assembly comprising:
A camera device comprising a lens, a camera shutter, and a switch assembly for focusing an image entering said lens and activating said camera shutter, said switch assembly comprising:
