High Pressure Limit Switch

The switch makes sure the furnace is operating safely and at its desired settings.

High pressure limit switch.

Standardized limit switches are industrial control components manufactured with a variety of operator types including lever roller plunger and whisker type. Switches are single pole double throw spdt so they switch one circuit on or off. High and low pressure switches may be installed on the refrigerant tubing of some air conditioning systems. However they are commonly found on heat pumps.

They are often used in pump and hydraulic power applications. It s also known as a fan limit switch or simply a limit switch. Rated ip69k these switches can withstand high pressure high temperature washdowns and temporary submersion. This pressure will be based on specifications for maximum pressure for the refrigeration systems high side and the type of refrigerant used.

Compact safety limit switches. The key is to protect the compressor from extremely high pressures that could damage. Long distance light beam. Limit switch is a switch operated by the motion of a machine part or presence of an object they are used for control of a machine as safety interlocks or to count objects passing a point.

The high temperature limit switch is an important device used in forced air furnaces powered by gas or heating oil. The high side if equipped with a high pressure switch should be set according to the manufacturer s recommendation. Designed for high pressure applications these switches electrically activate automated controls or alarms when a set pressure is reached.
