A shock protection circuit utilizing an immersion detection current interrupter for use in small electrical appliances wherein the combination of a solenoid or a relay plus a sensor will cause an interruption of the power leads of a small appliance and the mechanical latching of the relay or solenoid contacts in an open position when the presence of an electrically conductive fluid is detected. In one embodiment, the sensor remains conductive at a safe level, while in a second embodiment power to the sensor is also interrupted. Both embodiments are immune to electrical noise.
