To turn “ON” the device, touch the “ON” plate with your finger and to turn OFF the device, touch the OFF plate. When power supply is applied to circuit, the device connected through the relay (we have connected a light bulb) remains OFF. HAND OFF AUTOMATIC CONTROLS | electric equipment Hand off automatic controls are used to permit an operator to select between automatic or manual operation of a motor. The circuit shown in Figure 27–1 permits a motor to be operated by a float switch or to be run manually. The switch is shown as a single pole double throw switch with a center Off position. Toggle ON OFF Switch Electronics Lab Diode D1 is used to protect transistor from back voltage generated when relay goes off. A disadvantage of this circuit is that when we connect power to the circuit relay is engaged. A solution to this can be found on the second reference website below. Circuit is in OFF state Push button is pressed and circuit goes to ON state. Simple Hall Effect Latching ON OFF Relay Switch Circuit Handy circuit for switching ON or OFF any 120V or DC powered device or circuit. To trigger the relay ON, you simply bring one pole of a magnet within close proximity of the hall effect sensor. To...
