ABSTRACT:
A wiring device common in household circuits includes a flexible brush that is a separate piece from a screw plate that receives electrical power. A terminal screw can thread into the screw plate. The brush may be positioned between the screw plate and the head of the terminal screw and can have a clearance hole through which the threads if the terminal screw can pass. Good electrical and thermal conductivity is assured between the screw plate and the brush by tightening the screw. A ground strap can be employed to hold a cover to a base of the electrical device. The strap can include openings which engage snap tabs on the cover to lock all components into a complete assembly. The strap also can have hooks which engage the cover to prevent the cover from being pulled out of the strap. The wiring device can be an electrical switch, a receptacle, or any similar type of device.
