Dorman 911-606 Vacuum Switching Valve Compatible with Select Lexus/Toyota Models

Product Information

Wiring a pressure switch will largely depend on the particular device and the application where it is being installed. As such, you should always read the manufacturer’s guidelines for your specific model and be sure to familiarise yourself with it before completing any work.

Our single pole vacuum switches come in two variations: single or double throw. It’s important to understand the roles of each switch when buying a vacuum switch for your needs. Poles A single pole switch has just one input and one output, meaning it has just two statuses – either on or off. When wiring these switches, it’s possible to configure them either normally open or normally closed. If you need to generate vacuum, why not do it while consuming significantly less air at the same time? Prior to effective engine control unit computers, engine vacuum was used for many functions in an automobile. Vacuum switches were employed to regulate this flow. For instance a dual port vacuum switch located in a port on the intake manifold monitored the coolant temperature in the coolant crossover. It received vacuum (port E on the switch) from the carburetor. The vacuum flowed through the switch to a vacuum solenoid (such as a heat riser, used to restrict exhaust allowing the engine to heat up faster). When the coolant heated to operating temperature the vacuum switch closed off the port (port S on the vacuum switch) turning off the vacuum to the heat riser. The result is to clear the exhaust restriction. The switch monitored the temperature and when conditions were right it performed its designed function. As a point of note, while many manufacturers have yet to transition from 7-bar standard shop pressure, optimal vacuum operation takes place at an average of 4 bar. So, by accepting the challenge of a 4-bar factory, you can benefit your bottom line and the future of the planet without losing any efficiency.

This switch, when triggered, allows antifreeze into the inside of the heater core. This makes the heater work and reduces air temperature.

If you're looking for the best products for your industrial vacuum system, SMC has just the solution. From our vacuum filters to our vacuum regulators and vacuum gripper systems, we're always aiming to increase efficiency, save energy and ensure high performance. The result should be between 33 and 39 ohms under normal conditions. The VSV is having some trouble if the reading is out of this range. Step 3 With our vacuum filters, you can extend the lifespan of your components and lower your maintenance costs. Finally, you apply voltage while blowing air. You can use cables from the battery terminals to transmit battery voltage throughout the VSV terminals. The vacuum switching valve (VSV) regulates the vacuum supply to the actuator. It is usually closed and only opens when the electronic control unit energizes it.Single throw switches close a circuit in one position while a double throw switch has the capability for closing a circuit in two positions. Double throw switches also have a neutral position where neither circuit is activated. Where Vacuum Switches can be Found
