Trane SWT2532 SPST Pressure Switch

The Trane SWT2532 SPST Pressure Switch is an on/off high amperage switch used to regulate pressure in all HVAC systems. It is an SPST type, which means that the circuit has one set of contacts, in on and off position. This switch can detect pressure on a system and send an electric output when a particular pressure is attained within the system. it can switch on a fan whenever the pressure falls and switch off a compressor when pressure rises beyond a stated limit. These pressure switches are traditionally used in air handling units, fan coil units, and other HVAC systems where constant air pressure needs to be kept an eye on. Increased system efficiency and performance due to the right pressure level in the system.
