Abstract

A draw (2) for an electrical cabinet has two switches (4, 5) arranged next to one another and each with a drive shaft (6, 7). A locking device ensures that only one of the switches (4, 5) can ever be actuated, and that this is possible only when the draw (2) is in a position in the electrical cabinet provided for this purpose. The locking device comprises a two-armed lever (13) having detent noses (12) and a projecting detent lever (15) with a recess (16), and a respective detent disc (8) with a recess (10) for each of the drive shafts (6, 7) of the switches (4, 5). A tension spring (22) exerts a symmetrical return force on the two-armed lever (13). The device described is intended for switch installations with draws, for example motor control cabinets. <IMAGE>
