Galley kill switch.
Located on the top of the counter at the galley sink area.
When the galley sink is raised into position, the switch is pressed by the weight of the sink system and 12 volt power comes on.
When the sink is lowered to the floor, the switch releases and 12 volt power is disconnected.
This switch is important because it performs a critical safety function for the pop up. By automatically disconnecting the 12 volt power, the 12 volt ceiling lights cannot be left on accidentally when closing the unit. If the lights are on when the pop up is closed, the canvas that is touching the lamps can be ruined by the heat generated by the bulbs.
