1. A switch assembly comprising:
- a lower surface;
a push key supported above the lower surface and moveable with respect thereto;
the push key comprising an elongate member having a first end portion and a second end portion, a first switch being aligned with the first end portion, and a second switch being aligned with the second end portion;
the first switch comprising a first upper contact supported above a first lower contact, the lower contact being supported by the lower surface, both being aligned with the first end portion, and a resilient member acting to separate the first upper contact and the first lower contact, the resilient member aligned with the first end portion;
a locking ring extending from the push key through one or more arms curved substantially perpendicular to the push key, the one or more arms comprising a resilient material, the locking ring configured to receive a locking post; and
at least one of the first and the second switches configured to be closed upon movement of the push key;
wherein the resilient member, the push key and the one or more arms are constructed as a single element.

Abstract
A switch assembly is provided to actuate a pair of switches using a single push key. 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 a contact pad switch and a dome switch that are located laterally to one another. When the push key receives a first downward force, only the contact pad switch becomes activated and a first electric circuit is completed. When the push key receives a second downward force that is greater than the first force, the dome switch collapses and a second electric circuit is completed.
