What is a Mechanical Pressure Switch?
A mechanical pressure switch is an electromechanical device that opens or closes an electrical circuit based on a specific pressure level. These switches operate using a diaphragm or a bellow that responds to changes in pressure. When the pressure reaches the predetermined set point, the mechanical movement either makes or breaks the electrical connection. This action can initiate alarms, stop motors, or activate additional equipment, making them pivotal in safety and control systems.
