Boss Part # HYD01622 Lift Rocker Switch 6 Terminal is used as the lift rocker switch for your Boss RT3 plow with the control switch box controller. Most plows will have the Handheld control or Joystick controller, which would have no use for this switch, however, some Boss plows have a box which is mounted in your vehicle cab and has (3) white switches on it. This switch is an OEM part which will repair your lift rocker switch if that specific switch on your control box is having issues.
