What is a Vacuum Switch?

A vacuum switch is a mechanical or electronic device that, when subjected to a certain amount of vacuum gas pressure, offers an electrical switching contact function that may be activated. It is used in a variety of vacuum applications for the regulation of pressure and the provision of safety interlock.

It is possible to use a vacuum switch to regulate the pump and prevent it from running at excessively high pressure in a multistage turbomolecular pumping system by using a vacuum switch.

The fore-line vacuum pump is responsible for maintaining the fore-line vacuum pressure necessary for the turbomolecular pump to function properly. After reaching the predetermined switching point, the vacuum switch closes a relay contact, enabling an electrical signal to be transmitted to the turbomolecular pump, causing it to begin operating.

Please don’t be concerned about being overwhelmed by the number of options available; we realise how confusing it may be. If you find yourself in a bind, get in touch with a member of our helpful staff at PVL, who will be happy to assist you.

Our pressure and vacuum switches are widely utilised in a variety of industries and industrial processes. Our switches are utilised in a variety of industries, including hydraulics, pneumatics, and food processing, as well as chemical and petrochemical production and distribution.
