<p>An immersion detection current interrupter circuit with an electric latch for use in small electrical appliances. A sensor wire (W) is positioned within an appliance to sense current leakage when in contact with a conductive fluid. A relay or solenoid (R) connected to the sensor is positioned between the load leads (R) in a latch circuit. When the sensor detects a leakage current, it causes a two-pole double-throw relay to latch, breaking the load lines beyond the relay (R). The relay will remain latched untill the power cord is unplugged or reset by a switch which opens and closes the power lines. Once the component has latched, the maximum leakage current will be limited by the voltage drop across a diode (D5).</p> |
