ABSTRACT OF THE DISCLOSURE Disclosed is an electric switching device of the type having a contact system including two stationary contact bars and movable contact bridges for interconnecting the bars. To convert the switching device from a circuit maker to a circuit breaker, or vice versa, there is provided a control member in the form of a shiftable slide having insulating projections which in one end position of the slide are displaced between one bridge and a contact bar while the other projection is out of the range of movement of the bridges, and in the other end position the other insulating projection interrupts the contact between the other bridge and the assigned contact bar. In a modification, the converting member is in the form of a swingable arm cooper- ating with a slidably supported cam track which is turnable by 180°. -1-
