    Style B

    Style E

    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).
