ABSTRACT:
An electro-mechanical reversing contactor is disclosed in which a single common base is molded to receive two contactor powerheads. The common base has a bottom surface and upwardly extending sides, with an upwardly extending center divider, thereby forming two powerhead sockets. Each powerhead socket is capable of receiving a powerhead therein. The common base also has a circuit board pocket to receive a single circuit board to control both contactor powerheads. The center divider has an upwardly extending interlock tower to receive an interlock pawl that is engageable with each of the contactor powerheads. The interlock mechanism mechanically prevents both contactors from being energized at the same time. The common base for two powerheads saves labor and material costs in assembling and installing a reversing contactor.
