Abstract
An installation switch has an insulating housing and a terminal connecting arrangement for clamping a connecting conductor having an annular terminal shoe. The terminal connecting arrangement includes a terminal socket having an interior disposed between an insertion opening for receiving the terminal shoe and an access opening and a terminal screw having a screw head and a screw shank disposed in the interior of the terminal socket, the screw being actuatable in a longitudinal direction within the interior of the terminal socket between an open state and a clamped state. The arrangement further includes a connection plate having a screw hole with interior threads for threadably engaging the terminal screw when in the clamped state and a retaining device preventing the terminal screw from being removed from the terminal socket when in the open state.
