发明名称 Manual switch for direct current reversible electric winch motors
摘要 A manual switch for direct current reversible electric winch motors, which switch includes a switch housing that may be mounted on or built into the winch housing of an electric winch or connected by means of appropriate wiring to the electric winch motor for operating the winch under circumstances where automatic operation of the winch is not possible. The switch housing includes four fixed contacts that are electrically isolated from each other and from the housing and a pair of contact bars which are spring-loaded inside the housing to facilitate selective engagement with the respective fixed contacts responsive to manual operation of the switch to operate the reversible electric winch motor in the forward or reverse direction. The contact bars may be moved directly by hand manipulation of a handle-turret assembly attached to the switch housing or by a push-pull knob arrangement or more remotely, by energizing a pair of solenoids attached to the switch housing or a rotary actuator mounted on the switch housing or manipulating a remote handle connected to a remote handle bracket attached to the turret assembly of the switch housing by means of wires.
