A high pressure limit switch will be found in which type of circuit?

A high pressure limit switch is primarily found in an operating control circuit. This type of circuit includes devices that manage the operation of equipment by regulating its performance, ensuring safety and efficiency during operation. The high pressure limit switch monitors the pressure in the system and is designed to automatically interrupt the power or control the equipment if the pressure exceeds a predetermined limit, thus preventing potential hazards associated with overpressure conditions.

In contrast, safety limit circuits are generally designed to act as last-resort safety mechanisms that intervene when there is a failure in the operating controls. A power supply circuit pertains to providing electrical power to the system but does not directly control operational parameters like pressure. Auxiliary control circuits often have roles such as providing additional functionality or control features, but they do not directly serve the primary function of monitoring and controlling operating conditions like the high pressure limit switch does.
