The pressure switch has a tube that is open and goes into the water out of the washing area. As water rises in the tank it raises the pressure on the switch, when it reaches a preset level it trips. What you are asking I think the switch with the three contacts is a safety switch there is probably another switch to control the level or it could be done with a timer, both methods are used.
