Abstract

An installation switch having a housing and a connecting arrangement for a conductor having a terminal shoe. The connecting arrangement includes a socket having an interior, an insertion opening, and an access opening, and a screw having a screw head and a screw shank disposed in the interior of the socket. The screw is actuatable longitudinally between an open and a clamped state. The arrangement further includes a connection plate having a screw hole with threads for threadably engaging the screw when in the clamped state, and a retaining device preventing the screw from being removed when in the open state. The arrangement is configured so that the open state allows the shoe to be inserted into the insertion opening, the clamped state provides the screw being engaged with the shoe, and access to the screw is provided via the access opening of the socket to actuate the screw.
