In the case of this interruptor bracket, each connecting piece (30, 30') carries a sprung contact element (31, 31'). In the quiescent position, the two contact elements (31, 31') rest on at least one contact point (32, 33) with contact pressure on one another, and form a short-circuiting link for the connecting elements (30, 30'). A plug strip (37) having two mutually insulated contact tracks (39, 39') can be pushed between the contact elements (31, 31') in two positions. In the intermediate pushed-in position (Fig. 3b), the two contact elements (31, 31') are connected to one contact track (39'). In a final pushed-in position (Fig. 3c), each contact element (31, 31') is connected on its own to one contact track (39, 39'). In the case of the contact elements (31, 31'), preferably two contact points (32, 33) are provided of which, in the intermediate pushed-in position, only one is interrupted by the plug strip (37). In order to produce contact pressure, contact rockers (35) are in this case recommended which, when the first contact point (32) is open, reinforce the contact pressure on the closed, second contact point (33). In order to separate a cable connection, without interruption, from a transmission line, for example in a telephone system, which is to be measured, such interruptor brackets can be used as short-circuiting plugs for normal plug bases or as plug bases themselves for bracket areas. <IMAGE>
