Wasco Inc. is a highly recognized manufacturer of pressure and vacuum switches that supplies the Semiconductor, Automation, Fluid Power, and Hydraulic industries.

Wasco has been in business since 1963. Initially through the utilization of automatic screw machines and other machine shop equipment, Wasco manufactured parts for other customers. In 1975 Wasco started working on a pressure and vacuum switch product line utilizing existing equipment and many years of previous pressure switch design experience. Since then, three CNC bar fed turning machines were purchased to provide more unique and efficient designs. Research, development and testing equipment purchased through the years have assisted in proving out the more sophisticated applications to our customers.

Wasco’s has an entire range of precision miniature pressure and vacuum switches. This includes models certified not to leak at the rate greater than 1 X 10 -9 cc/second of helium and manufactured in a class 100 clean room.
