ABSTRACT:
A switch housing having a separate base attached to one end includes an electric end contact secured to each end of the base inside the housing, and central electric terminal means secured to the central part of the base between the end contacts. An elongated bridging contact engages the central terminal means and has end portions beside rigid dielectric members projecting from the base adjacent the end contacts for restricted lateral movement of the bridging contact. The end contacts have projections overlying the end portions of the bridging contact, and the base and all of the contacts and terminals together form a base unit in which the bridging contact is confined between the base and the overlying portions of the end contacts before the base is secured to the rest of the switch housing. Manually operable actuating means engage the bridging contact for rocking it on the central terminal means to electrically connect the latter with the overlying portions of either of the overlying contacts.
