  • Vacuum Switches: Surprisingly Exotic

    Pressure switches are important, if relatively obscure, utilities in a number of industrial, commercial and consumer contexts. They are regularly used in a lot of regular, relatively boring contexts, such as in automobile engines. However, they are also employed in some more exotic contexts. Take, for example, the CERN Nuclear Research Laboratory. CERN's Large Hadron Collider (LHC) laboratory is home to some of the most esteemed eggheads on the planet, all of whom are conducting some of the most complicated and expensive scientific experiments in history. The equipment of which...

  • CPR Micro-shields Share Qualities of Vacuum Switches

    In order to help regulate the pressure between two closed cavities, vacuum switches are used in many plumbing applications and old car engines. Check valves are probably the most common type of vacuum switch used today. These valves allow flow in only one direction and are often used in vacuum reservoirs. The medical industry uses check valves in non-rebreather masks, which deliver oxygen to patients in medical emergencies. I was a YMCA day camp counselor for three summers and every summer we were re-certified to administer CPR. I swear, they...

Industry Information

Vacuum Switches

Vacuum switches help regulate the pressure between two closed cavities by converting a negative pressure signal to an electrical output. As a safe and cost-effective alternative to safety relief valves, vacuum switches are able to work with gas, electric current and liquid pressure situations, individually or in a combination. In addition, pressure vacuum switches will detect when a problem, such as leaking pressure during operation, is happening and will shut down the process until the trouble is fixed and an operator restarts the operation.

Corrosion-resistant and long-lasting, vacuum switches provide control stability through inconsistent conditions and assure continuous service even under extreme shock and vibration. Often used to control and monitor various processes, vacuum switches are also commonly used in applications as an interlock device to sense gas, air or water pressure at a specific point, vacuum pressure switches provide on and off control of waste oil heating systems, residential boilers, electric heaters, pumps, small air compressors and transmission systems. Industries that utilize vacuum switches include food processing, aerospace, chemical processing, residential, industrial, commercial, heating and cooling, electronics and pharmaceutical. Automotive vacuum switches are the most common type of vacuum switches, and are used to regulate the flow of engine fluid.

Vacuum switches respond to a change in negative pressure. If a change is signaled, an elastomeric diaphragm opens or closes an electrical circuit based on a predetermined pressure set point and activates the vacuums switch. The movement of the diaphragm actuates a single snap acting switch, a mechanical switch that causes a rapid transfer of contacts from one position to another. When actuated, the snap acting switch converts the negative pressure signal into an electrical signal. An elastomeric diaphragm eliminates the need for an oil barrier because they separate pressure instruments from the process media, while allowing the instruments to sense the process pressure. A vacuum switch is set to a certain point of pressure to which it will automatically respond. Field adjustable pressure set points allow the vacuum pressure switch to be calibrated to the correct pressure points for opening and closing the diaphragm. There are three main vacuum switch designs: mechanical, pneumatic and electronic. In the mechanical and pneumatic versions, an elastomeric diaphragm reacts to changes in the pressure level and actuates either a mechanical switch or a valve. In the electric version, a piezoresistive pressure sensor measures the pressure level and converts the level into an electrical signal. Construction materials vary depending on the applications and vacuum switches materials are wide-ranging including brass, polycarbonate, plated steel, glass reinforced polyester, polyvinyl chloride and cast aluminum.
