Abstract (en)
[origin: EP0678889A1] One opening contact (3) of the emergency disconnection switch connects the positive pole (1) of a DC supply to the coils (a,b) of two auxiliary relays in parallel, in each instance via a parallel combination of an opening contact (Ka1,Kb1) and a closure contact (Kb2,Ka2). The switch has another opening contact (4) in series with that (5) of an ON button, between one relay (b) and the negative pole (2). The second relay is pulled-in before the first, discharging a memory capacitor (7) via a resistance (16) in parallel with a diode (8). The switching is indicated by LEDs (9,10). <IMAGE>
