Safety circuit in vehicle with operating voltage source feeding motor vehicle sets - has common supply line or group of vehicle sets functionally working in conjunction with each other across central switch controllable by control line
Safety circuit in vehicle with operating voltage source feeding motor vehicle sets - has common supply line or group of vehicle sets functionally working in conjunction with each other across central switch controllable by control line
The group of motor vehicle ancillary sets is connected with the operating voltage source, if at least one first motor vehicle set of this group is controlled. It is isolated from the operating voltage source, if no motor vehicle set of this group is no longer controlled. The voltage supply of the supply line and the control line are tested as to their plausibility. The motor vehicle electrical ancillary sets, functionally working together are dependent of the voltage supply of the control line from the ignition switch, and the central switch is a relay. ADVANTAGE - Safety switch designed, so that it has small number of switch elements for operating voltage supply, and has low failure probability.
