Economy Vacuum Switches
Choose these switches when you need reliable switching but not high accuracy. When they reach a set vacuum, they turn equipment on and off, signal automatic controls, or trigger alarms. They are single pole, double throw (SPDT) and can be installed to turn one circuit from off to on (normally open) or from on to off (normally closed). All meet American and European safety standards since they're UL recognized components and CE marked.
