Abstract: An infinitely adjustable control switch for controlling electric heaters in a domestic cooking range is disclosed. The control suited provides a boxlike housing which encloses two power switches and a switch for an indicator light. All of the switch components are supported by terminals positioned in a row along one side wall of the housing. Therefore, a unitary multiconductor can be used to simultaneously connect and disconnect all of the terminals. The terminals are installed in grooves formed in the side wall of the housing by lateral straight-end movement through lateral openings and without any movement lengthwise of the terminals. The terminals are then staked and a locking bar is installed to complete the mounting of the terminals and the switch components. Some of the terminals are provided with extension to support switch components at remote locations. Further the housing is provided with projections which position such extensions.

Abstract: A screw mount control and adapter combination permits the screw mount control to be converted to a bushing mount control. The control cover is provided with a pair of openings therein through which screws are threaded when the control is mounted in its screw mount configuration. A bushing mount adapter is installed on the screw mount control by pressing projections on the adapter into the screw openings in the screw mount control. The material of the adapter is softer and more ductile than the material defining the screw openings in the control so that a simple press-in assembly is provided.
