Pressure Switch Part Numbers Pressure Switches: The SQ range of compact pressure switches are manufactured with quality in mind, unlike many other manufacturers who’s products mechanical life is 1 million cycles the SQ range has a mechanical lifetime of 1.5 million cycles when operated below a pressure of 50bar. Pressures from 0.2bar to 100bar can be accommodated with either factory fixed or adjustable pressure ranges. With a choice of Diaphragm materials the switches can cope with a variety of chemicals including compressed air, hydraulic oil, engine oil, heating oil and water. The Comus International group of companies consists of: Please scan this quick response code with your QR enabled smartphone Pressure switch Hex size Body material Contact type Diaphragm material Connection fitting Screw thread Pressure rating Pressure switch How a Pressure switch works: A pressure switch works by a rubber disc (the diaphragm) changing it’s shape when subjected to pressure from either a fluid or a gas. This deflection of the diaphragm in turn pushes a small rod or piston which connects to a set of contacts via a spring. When the pressure is enough to overcome the tension of the spring the contacts will either open or close depending on the set up thus making or breaking the connection. This action can be utilised in many applications such as alerting when pressure drops in medical equipment, cutting of power to machines in the event of a fault, warning and controlling of air or oil pressure and detection of leaks in pressurised systems.
