ABSTRACT:
By providing a key actuated tumbler, rotationally journaled in a housing in juxtaposed spaced relationship to a pair of contacts, one of which comprises an elongated resiliently flexible member, with the tumbler incorporating actuating means for controllably moving the flexible contact from its first non-conductive position to its second conductive position, an inexpensive, easily manufactured and installed electric, key-controlled switch lock is achieved. In the preferred embodiment, the tumbler is mounted in a housing which incorporates a contact holding zone for positioning and maintaining the tumbler and the flexible contact in juxtaposed spaced cooperating relationship with the entire assembly directly mountable to a printed circuit board for initiating and terminating the flow of electric current thereto. In addition, in the preferred embodiment of the present invention, the tumbler incorporates an eccentrically disposed ridge formed about its outer peripheral surface as the actuating means for controllably moving the flexible contact between its two positions.
