    The traditional pressure switch. These power equipment, activate controls or alarms, or kick-off other actions when they reach a set pressure. Larger than compact pressure switches, they're easier to wire. These switches 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).

    Pressure Switches with CoverSwitches with a cover protect against impact and keep dust off the switch.

    Style JStyles A-C, E-J, and L meet at least one safety standard.

    IP66 Enclosure RatingIP66 switches withstand washdowns.

    NEMA 4X Enclosure RatingNEMA 4 and NEMA 4X rated switches can be used in dirty and wet areas exposed to washdowns and the weather. NEMA 4X also has increased protection against corrosion, similar to 304 stainless steel.
