1. An electrical switch assembly for use in a fluid line having a hose and fluid dispensing device, which comprises:

  • a housing defining a longitudinally extending fluid chamber, one end of said housing adapted to be coupled to said hose and the other end adapted to be coupled to said dispensing device;

    two reed switches adapted to be opened and closed by movement of a magnet in the vicinity thereof;

    means for mounting said reed switches in angularly spaced-apart relationship on said housing;

    manually graspable actuator means mounted for rotation about the longitudinal axis of said housing, said actuator means carrying a magnet for movement along a path overlying each of said reed switches; and

    biasing means for positioning said magnet at a central position in said path between said reed switches, whereby said magnet may be displaced by manual application of torque to the actuator means to energize the reed switch in the path of rotation and returned to said central position when said torque is released.
