When a preset pressure point is arrived at, a pressure switch has the ability to open or close a switch contact. Whether used with mechanical or electrical switch contacts, with displays or without, Pressure Switches offer an effective tool in an array of various industrious and technical applications. The GTS range of Pressure switches, both electronic and mechanical, ensure that you are provided with the perfect instrumentation for whatever your job demands.

Q: What is a pressure switch used for?
They are used in a wide range of industrial and residential applications such as HVAC systems, well pumps, furnaces, etc. A pressure switch monitors the system's fluid pressure and either opens or closes an electrical connection based on a preset pressure level. Some common applications of pressure switches include compressor pressure switches, air pressure switches and water pressure switches.
Q: How do pressure switches work?
When the inlet pressure force is greater than the springs pre-tensioned force, it switches the electrical contact. A Normally Closed (NC) contact will open, and a Normally Open (NO) contact will close. Once the pressure reduces, the contacts will return to their normal state.
Q: How do I choose a pressure switch?
We have a list of general attributes we look out for when customers inquire about our pressure sensors:
Maximum pressure; adjustment range; the medium it is being used for; process connection thread & type; normally open, normally closed or SPDT; electrical connection; voltage & current handling requirements.
Q: What is the difference between a pressure switch and a pressure sensor/transmitter?
Pressure switches operate electrical switches at a preset pressure level, while pressure sensors read the system pressure and convert it into an electrical signal.
Q: What are pressure switches used for?
Pressure switches are used in a wide range of applications in order to monitor pressure levels in air compressors, irrigation systems, HVAC systems, medical equipment, and industrial processes. Pressure switches are usually used to alarm or indicate that a pressure has fallen or risen too high. The pressure switch will usually activate an audible alarm, warning light, or both.
Q: How often should I maintain a pressure switch?
How often a pressure switch should be maintained depends on the application and environment the pressure switch is being used in. Usually, the process involves looking for leaks, loose connections or any visible damage.
