SPST A/R N/O Limit

The SPST A/R N/O Limit Control is a limit control that performs two different functions. It allows the homeowner to set a maximum temperate (maximum temperature) in the home, and it also indicates the current temperature. This dual function is especially useful in homes with heat pumps. This control will also help prevent domestic hot water (DHW) equipment and space heating equipment from being damaged by overheating.

An air conditioning (A/C) limit control shuts off the A/C compressor when the set temperature is reached. Usually used at the end of a branch circuit, it can be installed in the external weatherhead or in the ductwork. The SPST Switch allows for "on" (open) or "off" (closed) position.

For an old, reliable straight switch, this Rheem limit switch is perfect for your furnace. Because it's direct-acting, the switch only turns on when the compressor tries to kick back on. The black nylon PA bushings and a high amperage rating also ensure high durability.
