ABSTRACT:
An improved, low-cost magnetic switch assembly (16, 16a) is provided having an easily fabricated housing (24, 24a) and cover (29, 29a) formed of non-conducting synthetic resin material. A pair of electrically conductive switch elements (30, 32, 30a,32a) are positioned in spaced relationship with the housing (24, 24a) along with a body (40, 40a) shiftable between a first position in simultaneous contact with the switch elements (30, 32, 30a,32a), and a second position out of such simultaneous contact. The housing (24, 24a) is also equipped with a first attractive component (38, 38a) which magnetically reacts with the body (40, 40a) to hold the latter in one of the positions thereof when the assembly (16, 16a) experiences a first magnetic field condition, but allows the body (40, 40a) to move to the other of the positions thereof when a second magnetic field condition is experienced adjacent the assembly (16, 16a).
