Web27 de ago. de 2014 · A simple latching relay circuit requires a NC button (or a NC/NO button or switch, one that has both states depending on how its pressed/switched). As Vlad has shown. There is also a latching relay that depends on Acc/On switched power, where it turns off once the car is turned off, and only turns on when you press the button when … WebThis ON-OFF Switch circuit uses the well known 555 timer. The timer activates a relay through a bipolar transistor in order to connect or disconnect the device we want to control. Manual activation is performed through two momentary contact switches. Switch 1 (SW1) is used to enable and Switch 2 (SW2) is used to disable the device.
