HIGH LIMIT SWITCH 1/2 CONDUIT x 1/2 MPT

165C/320F 110V 25 AMP

A High Temperature Limit Switch is used on hot water pressure washers to prevent excessive water temperature. The switch is a bi-metallic, non-adjustable thermostat. When the bi-metallic sensor expands and bends, it breaks an electrical circuit when the water reaches a pre-set temperature. When the switch cools, the metal contracts and the circuit is again completed.

The sensor consists of two strips of metal bonded together. The strips expand at different rates when the temperature increases. The differing expansion rate of the two metals allows the sensor to bend. Normally the bi-metallic sensor will touch another contact. The control circuit runs through this connection. As the temperature rises, the bi-metallic sensor bends away from the contact and the circuit is broken, cutting power to the fuel solenoid.

NOTE: The thermostat will not reset until all areas surrounding the part cool down. This may result in a temperature drop of up to 50 degrees before the thermostat resets and starts the burner.

Thank you for browsing our selection of pressure washers, steam cleaners and accessories.

We have the tools you need to effectively use and maintain your pressure washer.  Quick connect and rotating turbo nozzles are available in various sizes and configurations.  It's important to use the proper size nozzle for your pressure washer.  Nozzles are sized by looking at the PSI and GPM of your pressure washer.  Quick connect nozzles make it easy to change spray patterns or replace nozzles when they are bad while using the same spray wand.

Pressure washer hoses and hose reels will help you reach your work area, and specialized spray guns with different angles and lengths of wands will make certain jobs easier.

To keep your pressure washer working properly, routine parts and maintenance could be required.  Pressure washer pumps, unloaders, and motors should match the specifications of your particular machine.  Hot pressure washers and steam cleaners require additional components like burners, ignitors, and fuel pumps to allow them to heat the water.

There are a number of different accessories for your hot or cold pressure washer to clean different areas.  Surface cleaners are great for cleaning large areas like parking lots, gas stations, industrial facilities, and school yards.  Duct cleaners are designed to clean trash-chutes, vents, ducts, restaurant hoods, tanks and more. Wet sand blasters can be used on various surfaces to remove most coatings down to white metal, for graffiti cleaning, or paint surface preparation.
