For displacing an electric switch (12) arranged in a compartment (10) which can be closed with a door (11) in a cupboard, also when the door is closed, a device is suggested which comprises a carriage (26) to which the switch can be fastened and which can be fed forward by an endless screw (21) secured thereto by means of a throughnut (27). The screw can be actuated through a bore (22) formed through the door by a tubular wrench (25) only after that a slider (35) has been shifted in order to give access to the wrench for a square-portion of the screw shank. Latching means (29, 31) are provided which make the shift of the slider possible only if the switch is OFF and which keep the switch OFF along the entire displacement span, the switch closure being permissible only in the end position of disconnected and connected to the main. |
