ABSTRACT:
An electrical wiring device having a housing with a first set of openings through which the bare ends of conductors are pushed to effect so-called push-wire connection of the conductors to terminals within the housing in the usual manner. A second set of openings is provided adjacent the first set and a reciprocally slidable member is positioned within each of the second set of openings. Using a small tool, the slidable members may be pushed inwardly to contact and move the spring clip holding the conductor in firm engagement with the terminal, thereby releasing the conductor and permitting its withdrawal from the wiring device. The slidable members include a central stem portion with protrusions extending outwardly in opposite directions adjacent the two ends thereof. The slidable members are configured to cooperate with portions of the wiring device in such a way that movement is constrained to a predetermined path between inner and outer limits.
