Abstract

A locking device for a switch arranged on a plug-in or slide-in unit comprises an adjustable element (1) rotatably mounted in the unit (17) which can be operated by a handle inserted at (2) to engage a plunger (3) and cause a Bowden cable (6, 7) to enter a recess in a locking mechanism of the switch. The cable (6, 7) is acted on by an intermediate member (5) connected to the plunger (3) and having a tongue (12) held against rotation by a slot in a member (13). The intermediate member (5) engages a flange (14) when the adjustable element (1) is rotated to draw the contacts of the switch together, and then drops into a recess in said flange, to unlock the switch, when rotation of the adjustable element (1) has been completed. The intermediate member (5) permits the handle to be inserted into the adjustable element (1) only if the switch is in the off position since the Bowden cable (6, 7) can only enter the recess in the locking mechanism when the switch is in this position. <IMAGE>
