A switch assembly for a lift unit includes a switch, an emergency stop device, and a reset actuator. The switch is arranged to move between a closed position, wherein the switch electrically couples a lift motor of the lift unit to an energy source, and an open position, wherein the switch electrically decouples the lift motor from the energy source. The emergency stop device is coupled to the switch and arranged to move the switch from the closed position to the open position. The reset actuator is coupled to the switch and arranged to move the switch from the open position to the closed position, wherein the reset actuator is controllable to move the switch from the open position to the closed position.
