  • Patent number: 4772765
    Abstract: A combined on/off and reversing switch, particularly for an electric screwdriver having a reversible motor, has a switch plate which can be rotatably mounted on an end of the motor. Terminals of the motor extend through the switch plate and are selectively contacted by ends of two resiliently flexible contact strips carried by the switch plate. An actuating member is moved along a selected path to rotate the switch plate to select "forward" and "reverse", and then depressed inwardly to flex an end of the appropriate contact strip to complete energization of the motor. The contact strips resiliently bias the actuating member outwardly to switch the motor "off" when the actuating member is released. Switching the motor "on" from a neutral "off" position of the switch involves a two part movement of the actuating member. The switch is of simple and compact construction.
