ABSTRACT OF THE DISCLOSURE A conductive touch grid or plate incorporated in the handle portion of apparatus such as an appliance performs the on/off function of the appliance as well as sensing the impedance of the operator with respect to either the line or neutral side of an associated AC source. Whenever the sensed impedance indicates a potentially dangerous condition a switching element in series with the line conductor interrupts current flow to the appliance thereby protecting the operator. 2.
