Abstract
A pressure-actuated switch having a pressure port, a diaphragm, a range spring, an actuator plate, a differential plate, and an electrical switch. A certain pressure level moves the diaphragm against the range spring at the pressure port and thus deflects the actuator plate. The actuator plate is coupled to the electrical switch via a snap spring, wherein the electrical switch can be switched on or off via the deflection of the actuator plate and the snap spring. The differential plate controlled by a differential spring is connected to the actuator plate and supports the actuator plate in a first portion of movement, wherein the differential plate is decoupled from the actuator plate in a second portion of movement of the actuator plate.
