FIELD: relay automatics. SUBSTANCE: switch has two polarized relays with two-stabilization modes, with switching-on and off winding, with two-position adjustment of contact system, make and break contacts. In addition there is break contact of additional relay, make contact of auxiliary relay and input to start program-time device. In common circuits of switch there are used first and second diodes, button of common reset with contact, additional control button with make contact, common resistor and thyristor. Each channel includes five common leads-out, four diodes, thyristor, relay winding make contact of control key and make contact of starting button. Switch uses make output contact of program-time device which closes on completion of preset time program. This contact is held in closed state for the course of time after start command across input of program-time device beginning from moment of termination of realization of preset time program and return of this contact into initial break condition after removal of start command at input of program-time device. Output make contact of program-time device sets switch into starting position automatically. Remote transfer of switch into starting state is also possible by means of reset button with make contact. additional control button with make contact is inserted and used to set additional relay into starting state. Its break contact closes starting circuit of program-time device. Common thyristor ensure starting of additional relay and not switching on of it after additional button is disconnected with make contact. Channel thyristor is started with the aid of starting button and corresponding diodes which makes it possible to start winding of switching on of channel relay and to keep it later in switched-on state without use of contacts of relay of this channel. EFFECT: enhanced operational reliability. 1 dwg
