<p>A low voltage switching device has a two-part housing (2) that is fastened at the rear (3) to a rail. Inside are several printed circuit boards (33) which are parallel to the connection side (14) of the housing. The boards each have a row of screw terminals (31) at one end. The openings for connecting wires at the terminals are at right angles to the plane of the boards and are accessible through holes (21) in the housing. The screws for the terminals are also accessible (by a screwdriver) through holes in the housing. There are guide rails in the housing to hold the circuit boards.</p> |
