Abstract
The present invention relates to a switch-fuse unit provided with a control block to activate auxiliary circuits, this control block being provided with a rotating shaft fitted with a handle for selecting the unit's functions. This unit comprises an accessory device (10) mounted on the control block (11) and is provided with at least one microswitch (13) associated with an auxiliary circuit and a rotating part (18) mounted on said rotation shaft, this part being fitted with at least one activation cam (17). Each microswitch (13) comprises a mobile actuator (14) controlled by a plunger (15) via a support (12), this plunger (15) itself being controlled by the activation cam (17) associated with it, when the rotating part is moving. This accessory device (10) is particularly compact, easy to access and use and is suitable for all switching logics.
