ABSTRACT:
Electromagnetically operated contactor employing contact modules which are converted from normally open to normally closed and from normally closed to normally open operation by inverting the contact module in the contactor. The contact terminals of the contact module are clamped by various arrangements against conductive members of the contactor. Wiring terminals for connecting external wiring to the conductive members are spaced from the arrangement for clamping the contact terminals to the conductive members. Thus, the wiring terminals and the external wiring do not interfere with the module or arrangement for clamping, and the module may be removed, inverted, and replaced without disturbing the external wiring connections.
