Series 7000 Vacuum Pressure Switches provide reliable and repeatable snap-action switching in response to vacuum pressure in a ruggedly constructed miniature type package. Designed and tested to MIL-Spec quality standards, these switches can be furnished with a variety of electrical connectors and pressure ports. In addition, the design construction ensures capability of withstanding a positive proof pressure of 60 psig.

The Series 7000 Vacuum Switches are capable of meeting severe MIL-Spec type environments such as shock, vibration, and temperature cycling.
