Abstract
A switch housing extends to enclose wiring terminals, incorporating holes for insertion of wire conductors and for accessing a clamping screw assembly with a tool to clamp the conductor against the terminal. Individual cavities for each terminal are substantially sealed against ingress of dust, electrically isolating the terminals, and preventing removal of the screw from the respective cavity.
