ABSTRACT:
The safety switch assembly is designed to provide a switch assembly to a tool, such as a meat slicer, in order to prevent the operation of the tool without manually holding the pressure sensitive safety handle. The assembly contains a control box having a ground fault interrupter/on-off switch, signal device, a power receptacle and a control circuit. A safety handle is installed on the tool and the handle has two pressure sensitive strips which function as a dual force sensing resistor and is connected to an electric cable that connects the safety handle to the control box which houses the control circuit. The operation of the tool requires that power be supplied to the control box. When the individual grips the safety handle and squeezes the handle, the control box provides power to the tool itself.
