TIME-DELAYED (TURN-ON) TIME RELAY SCHEMATIC CIRCUIT DIAGRAM

Time-delayed circuit with UJT and thyristor (turn-on type): C starts to be filled when S is closed in the given circuit. When the voltage of C reaches 6-9 V, the UJT will suddenly switch on. The voltage on R3 triggers the thyristor, the lamp illuminates. Pot and L start time can be set.
