This protective vacuum switch boot provides a layer of protection for a Presair vacuum switch. The rubber vacuum switch boot slips on over the switch to protect any electrical connections from the elements and environment where the switch is located. It also adds shock protection for any person near the switch.

By providing on/off switching from a pneumatic source, Presair pressure switches deliver critical benefits:

• Safe and Convenient: Remote operation with complete electrical isolation. UL Recognized.
• Economical: Costs less than conventional controls
• Accurate: Highly stable with good repeat accuracy. All switches are 100% tested at high and low settings and at proof pressure.
• Reliable: Minimal moisture absorption and maximal dimensional stability.
