Series V4000 vacuum switches convert negative pressure signals into electrical outputs using an elastomeric diaphragm to actuate SPST or SPDT electrical contacts for on/off control in pneumatic or fluid systems. The switches feature field-adjustable set points, 1/4" male quick-connect electrical terminals, and are available with mounting and pressure fittings in stainless steel, injection molded plastic, or plated steel. Vacuum ranges span from -2.5" W.C. (-600 Pa) to -10.75 PSI (-75 kPa). Electrical ratings reach 25 A at 250 VAC, with operation certified for reliability across temperatures from 32°F to 190°F (0°C to 88°C) and a rated life of 100,000 cycles under full electrical, mechanical, and thermal loads. The switches are UL recognized and CE approved for use as operating, limit, or safety controls.
Series 3000 pressure switches convert a pressure signal to an electrical output. In response to a change in pressure, movement of an elastomeric diaphragm opens or closes an electrical circuit based on a predetermined pressure set point. . .
