Abstract
A thermally responsive electrical switch for a fast idle control in an automotive engine has two thermally responsive snap acting discs disposed in an open-ended well in a thermally conducting housing. A switch having contacts movable between open and closed circuit positions is disposed in the open end of the well and the discs are arranged to snap at respective first and second temperatures to move the contacts from one circuit position to the other and then to return to the original circuit position in sequence as the disc elements are successively heated to said first and second temperatures. Resilient conductors are mounted on the switch and are electrically connected to the respective contacts. A terminal which completes the low cost assembly is secured to the housing to press terminals of different selected types against the resilient conductors to electrically connect the terminals to the respective switch contacts and to resiliently hold the switch in place in the housing.
