description The present invention provides an overload protection circuit having a first switch connected at a first side to a source of electrical power and at a second side to a load, the switch having on and off modes and a second switch connected between the first switch second side and ground, the second switch having on and off modes. A control module generates at least one signal controlling the first switch mode and the second switch mode wherein the signal turns the second switch to the off mode when turning the first switch to the on mode and the signal turning the second switch to an on mode when turning the first switch to the off mode. Both over current and leakage protection are thereby achieved.
