Abstract
An ignition switch for the selective ignition of a gas tap assembly that is controlled by a rotatable gas tap spindle is disclosed. The switch has an aperture which receives the gas tap spindle. Opening and closing of the gas tap is achieved by rotation of the spindle. Rotation of the spindle causes rotation of a cam in the aperture of the switch to control the making and breaking of a pair of electrical contacts. The contacts have relatively thick terminal portions that are secured in the housing with their outer ends extending into openings which receive insulated sockets. The contact members are L-shaped and have relatively thin contact portions which are positioned so that one portion overlies the other and both of them overlie the rotatable cam.
