Pressure Switches

Pressure switches are used in a wide range of industrial and manufacturing applications. Their function is to provide electrical feedback to systems in response to variations in pressure.

When the pressure rises or falls from a particular preset pressure level, the switch creates an electrical contact. Pressure switches are used in various industrial and domestic applications such as HVAC systems, well pumps, furnaces, and so on.

They are also known as pressure sensors since they are used to respond to fluid pressure. For example, pneumatic switches are used in compressors and pumps, while hydraulic switches are used in automotive engineering.
