A three-action pressure switch comprising a first electric switch that turns on and off when the contacts connect and separate, and a second electric switch that turns on and off according to the displacement of the second operating body, when the pressure is low. The pressure-receiving displacement mechanism is provided with reversing means for displacing the first actuating body in opposite directions and reciprocating depending on when the pressure is high and when the pressure is high. The first electric switch is turned on by causing the electric contact to follow the reciprocating motion of the first actuating body and contacting and separating the electric contact from the other electric contact.
A three-action pressure switch characterized by being turned off.
