Abstract
Embodiments of the invention provide a switch for use with an appliance valve, such as for gas appliances. The switch may comprise a base for coupling the switch to a valve, a rotatable hub in communication with the base and providing rotation therewith, a first protrusion projecting outwardly from the hub, and a detent disposed on the base and in communication with the first protrusion for resisting rotatable motion of the hub. Rotation of the hub in a first direction for turning an appliance valve to an on position requires the first protrusion to flexibly deflect the detent to permit the hub to rotate past the detent. As a result, danger of inadvertent rotation of the switch is reduced.
