The safety switch is for rail vehicles without pneumatic brakes, e.g. trams with electrically controlled brakes and brake controls (BSG1,BSGn). A signal line lop (SS) runs from the end of the train to the beginning of the train and back again. This line has a signal creation sector (SE) starting from the supply source. This sector is connected with a signal distributing sector (SV) at its end, The signal creation sector has the brakes connected to it in parallel. Relay coils (RS1,RSn) are connected to the signal distributing sector. |
