Miniature diaphragm pressure switches

Euroswitch miniature pressure switches are available from LDA. Thanks to their design, these switches are ideal for installation in small devices, hydraulic systems, or industrial applications with limited installation space.

The housing is made of brass as standard (other materials available on request) and can withstand working pressures of up to 20 bar and overpressures of up to 50 bar. The pressure switches use silver contacts, suitable for switching voltages of up to 48 V (model 25R) or 12 V (model 25D), and switching currents of up to 8 A.

Both models feature a snap action mechanism with a service life of more than 100,000 switching operations, both mechanically and electrically. The set point and hysteresis can be factory adjusted on request for optimum performance.
