High Pressure Limit Switch

High and low pressure switches may be installed on the refrigerant tubing of some air conditioning systems.

High pressure limit switch.

Designed for high pressure applications these switches electrically activate automated controls or alarms when a set pressure is reached. 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. Compact safety limit switches. The switch makes sure the furnace is operating safely and at its desired settings.

Shorter and thinner than other safety limit switches these are sized to fit tight spaces. However they are commonly found on heat pumps. In the case of a heat pump in cooling mode the high pressure switch is used to make sure that outdoor unit can reject heat with the outside air. The key is to protect the compressor from extremely high pressures that could damage.

Switches are single pole double throw spdt so they switch one circuit on or off. Standardized limit switches are industrial control components manufactured with a variety of operator types including lever roller plunger and whisker type. The high temperature limit switch is an important device used in forced air furnaces powered by gas or heating oil. Long distance light beam.

They are often used in pump and hydraulic power applications. Rated ip69k these switches can withstand high pressure high temperature washdowns and temporary submersion. They can be wired normally open no or normally closed nc.
