Switch assemblies, rail-mounted lift systems, and rail-mounted lift units having emergency stop devices

A switch assembly for a lift unit, the switch assembly comprising:

• a switch 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;
• an emergency stop device coupled to the switch and arranged to move the switch from the closed position to the open position;
• and
• a reset actuator 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 and reset the emergency stop device.

A rail-mounted lift system comprising:

• an overhead rail;
• and
• a rail-mounted lift unit arranged to traverse the overhead rail, the rail-mounted lift unit comprising:
• a lift motor;
• a switch arranged to move between a closed position, wherein the switch electrically couples the lift motor to an energy source, and an open position, wherein the switch electrically decouples the lift motor from the energy source;
• an emergency stop device coupled to the switch and arranged to move the switch from the closed position to the open position;
• a reset actuator coupled to the switch and arranged to move the switch from the open position to the closed position;
• one or more user interface devices comprising a touchscreen display, and
• a control unit comprising a processor coupled to a non-transitory memory storing computer readable and executable instructions, the control unit being communicatively coupled to the reset actuator and the one or more user interface devices, wherein the control unit executes logic to:
• receive a reset input from the one or more user interface devices;
• and
• move the switch from the open position to the closed position with the reset actuator and reset the emergency stop device when a reset input is received by the one or more user interface devices.
