Preset or Adjustable Vacuum Switches

Nason’s vacuum switches offer 100% reliability and can be used in designs that accommodate 1" to 30" of vacuum. Construction of the vacuum switches is consistent with our pressure switches utilizing a long-life elastomer diaphragm that engages a snap-action design micro-switch for consistent and accurate operation. You can order your switch with a factory preset or make it field adjustable - depending on your design requirement.
