ABSTRACT:
A shock hazard protector for protecting small appliances from the presence of water. The shock hazard protector utilizes a fusible wire link mechanically connecting two opposing resilient electrical contacts. A triac is connected to a sensor circuit and, upon the occurrence of water in predetermined parts of the appliance, the triac fires and causes a current to be passed through the fusible link to melt the link, release the resilient electrical contacts and open both power line simultaneously.
