York S1-024-25329-704 Pressure Switch 1.9"-WC SPNO Close On Fall

The York S1-024-25329-704 pressure switch is designed for HVAC use only. It is an essential element that senses pressure fluctuations in the entire system and takes the necessary action. It has 1.9" WC pressure, and it is a Single Pole, Normally Open (SPNO) type, which means it will be closed only when the pressure is low. This particular pressure switch plays an essentialrole in making sure that the operations of the HVAC system are appropriate as well as safe. The present invention can cause various system activities such as compressor starting, fan functioning, and safety stoppage if the pressure is detected correctly. This contributes to regulating pressure to issue standard temperature and humidity and also avoids cases where equipment, is destructed by different forms of pressure.
