ABSTRACT:
Two relays and a push-to-start switch are mounted together on a common frame within a common housing. The cores and coils for the devices are mounted in spaced parallel relationship on the frame. Three legs which extend from one side of the frame are supported adjacent an edge of an insulated terminal strip which latter supports the terminals, contacts, and contact arms for the devices. Two legs which extend at right angles to the first-mentioned legs and which are bent from spaces therebetween are received by slots in a base plate which is also slotted to receive portions of the terminal strip and the frame to support the same. Recesses are formed in the housing member adjacent to the base plate to allow insulated conductors to enter the housing. The recesses contain teeth that bite into the insulation over the conductors to prevent them from being moved longitudinally.
