Fixed Setpoint Vacuum Switches

Prevent changes to the set vacuum that powers equipment, activates controls, or signals alarms. The setpoint on these switches isn't adjustable. They’re single pole, double throw (SPDT) and can either turn one circuit from off to on (normally open) or on to off (normally closed).
