Abstract
The present invention defines a convertible elec-trical contact. The convertible contact comprises two pairs of movable contacts attached to an actuator which is supported by and enclosed within a housing. The ac-tuator is biased to a first position and is slidably mov-able to a second position in response to a force applied to the actuator. The movable contacts are attached to the distal ends of a flexible member which is supported at its approximate midpoint by the actuator. The mov-able contacts are also movable between a first position and a second position as the actuator is moved. A pair of contact cavities are defined by the housing such that the one contact cavity lies on each side of the actua-tor and the flexible member and movable contacts are contained within the cavities. The housing defines a first pair of access apertures associated with the first position of the movable contacts and a second pair of access apertures associated with the second position of the movable contacts. A convertible stationary contact module which includes a pair of bussing conductors, each with a stationary contact attached at its end, is employed to complete the electrical contact. By selec-tively placing the bussing conductors and then asso-ciated stationary contacts in either the first or second pair of access apertures, either a normally closed or a normally open electrical contact can be chosen. The contact module is attached to the outside of the hous-ing by a mounting screw.
