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 secondary switch and the depression of a button. The assembly contains a control box having a ground fault interrupter/on-off switch, signal device a pneumatic switch power receptacle and a control circuit. A safety handle is installed on the tool and the handle has an actuation button and a safety button, which functions as a four way valve, installed in series, and connected to an air tube that connects the safety handle to the control box pneumatic air switch. The operation of the tool requires that power be supplied to the control box. When the individual depresses the safety and squeezes the button on the handle, the control box provides power to the tool itself.
