Automatic cycle switch circuit 2

Automatic cycle switch circuit 2 It uses 555 IC as the control element} A capacitive step-down circuit; bidirectional thyristor V control relays or loads on and off time. RPi a

djustment potentiometer and RP2 (or Cl), respectively, can be changed relay KA pull and release time. As will RPi raised 300k, 0, RPz adjusted 220kfl, the pull-in time KA 20s, the release time is 15s.
