Latching relays are nifty devices. Most contain two separate coils. When a voltage is applied to one coil the relay latches in one state and stays in that state until voltage is applied to the unlatch coil. Since the latching and unlatching pulses only need to last about 25 milliseconds, it is possible to control a sizeable amount of power using little energy. ........

DescriptionBy means of a Relay, employed to drive a water pump, this circuit provides automatic level control of a water reservoir or well. The shorter steel rod is the "water high" sensor, whereas the longer is the "water low" sensor. When the water level is below both sensors, IC1C output (pin #10) is low; if the water becomes in contact with the longer sensor the output remains low until the shorter sensor is reached.At this point IC1C output goes high, Q1 conducts, the Relay is energized and.......

This circuit can be used to activate a relay for two or three minutes. Pressing the switch the relay will be activated. Changing the 1M resistor with a variable resistor you can vary the time. The 0.01 capacitor is important because it prevents any false triggering. The circuit will work OK with 6 Volts without any modification. If you want to use 9 or 12 Volts, you need to change the relay with a 9V or 12V relay. Using this circuit with 120 VAC is not recommended, however, using the right parts.......
