Abstract
An electrical switch unit for use with an electrical device to control operation of a DC motor of the electrical device, the electrical switch unit comprising: a housing which houses a pair of electrical switching contacts, and, an actuator operably connected with at least one of the pair of electrical switching contacts, the actuator being configured for movement relative to the pair of electrical switching contacts so as to arrange the pair of electrical switching contacts into at least one of a closed configuration wherein power is able to be supplied from the DC power source to the DC motor via the pair of electrical switching contacts, and, an opened configuration wherein power is not able to be supplied from the DC power source to the DC motor via the pair of electrical switching contacts; a signaling module associated with the electrical switch unit comprising signaling circuitry for sensing the movement of the actuator and outputting a signaling module signal indicative of the sensed movement or position of the actuator; a power module comprising at least one power switching device for controllably supplying power from the DC power source to the DC motor; a control module c…
