The switch (1) includes a box-shaped housing body which can be installed in a switch cabinet. A switching lever (5) and an additional device (4) are arranged on the front of the housing body, which lever and device can be passed outwards through a door of the switch cabinet. On the front, the housing body has a flat bearing surface (6) of defined size from which the switching lever (5) projects. The additional device (4) has a flat rear which corresponds with the bearing surface (6) and with an opening (3) in the switch cabinet door. Fastening means are furthermore provided, with whose aid the additional device (4, 19, 22, 25, 27, 30) or a further additional device (19, 22, 25, 27, 30), which can be replaced thereby, can be fixed on the bearing surface (6).
