Abstract
Abstract A multiple circuit switch for use as an appliance timer is disclosed. The switch includes a housing and a disc rotatably mounted within the housing and having a cam face spaced from and parallel to a flat housing wall. A plurality of switches are provided between the cam face and the wall and are adapted to be opened and closed by concentrically disposed, radially spaced cam tracks on the cam face. The flat housing wall carries a plurality of flat conductors and each of a plurality of those conductors is electrically connected to at least one switch terminal, and each of a plurality of those conductors terminates at an edge of the housing in parallel alignment to other conductors for connection to other circuitry.
