Abstract: A first pole of a double pole switch selectively connects a battery to a motor in one switch condition and disconnects the motor and battery in a second switch condition, wherein a second switch pole connects a dynamic braking circuit around the motor. In the event contacts of the first pole weld closed and fail to open in the second switch condition, the second pole connects the fuse directly to the battery in shunt of the motor to cause the fuse to blow and open the circuit to the motor. Alternative embodiments incorporate time delays between switch operation and blowing of the fuse by incorporating a thermistor or an R-C timing circuit.
