made in u.s.a.
Presair switches are designed & manufactured in Eau Claire, Wisconsin U.S.A.
The PCB mount vacuum 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.
These versatile switches are a great choice for many applications due to their small size & variety of connection styles. Although these switches are built to connect to a printed circuit board, they can also be retrofittted for nearly any application by connecting wire leads. These switches can sense vacuum ranging from 6 inches of water all the way up to 200 inches of water.
