The pressure switch is a normally closed (low air pressure) switch that connects via a 3.5 mm jack into the back of the mounting plate on Legacy ATC’s. On the M style tool changers, they are located on the underside of the ATC electrical box, and are connected with two wire leads directly to the ATC board. When the switch has above 90 PSI it opens. The ATC control board looks for this open signal to indicate there is adequate air pressure.
