Series PCB Air Switch Specifications

Series PCB Air Switch

Series PCB air switches are single function controls with internal electrical contacts designed to mount directly to a printed circuit board. These basic component switches feature momentary switching logic in a compact design to add pneumatic actuation to any electronic control circuit. Tubing connectors accept 1/8" I.D. and 1/16" I.D. flexible plastic or rubber tubing and are available in either center hole mount or side spout configurations. Additional models with a 1/8" NPT connector are available. Designed and engineered to exceed 100,000 cycles under full mechanical, electrical and thermal loads, Series PCB air switches provide superior performance when used in conjunction with Tecmark® LectricAir® pressure transmitters or when used in pressure sensing applications requiring set points as low as 6" W.C. or up to 25" W.C.* (1.5kPa to 6.22 kPa)

Typical Applications

Series PCB switches provide remote actuation of electronic circuits that control motors, lights, pumps, air blowers, or other associated equipment. Additional models available for use in positive, negative or differential pressure sensing applications.
