Pressure switches are a form of switch used to make or break electrical contact after certain set pressure has been reached on its input, usually from a pneumatic or hydraulic source. Examples of the use of pneumatic pressure switches include the switching off gas compressors and switching on a warning lights of automobile when engine oil pressures fall below a safe level of ball valve.

Since the invention pressure switches, they have been used as a means of preventing injuries resulting from overloads or explosions. Most of the machineries involved in any type of production nowadays include pressure switches as part of a safety requirement.
