Questions

Question

For which pressure switch applications are gold contacts recommended?

Answer

For "dry circuit" applications where little or no current is flowing in the circuit to help burn off contact dirt and oxidation. Switches used with solid state circuits often fall in this category.

Question

Will the MVS series vacuum switch work if they are in the box with the vacuum. I need to signal when the vacuum in the box, in which the switch is placed reaches a level. The electrical connections are through a hermetic connector on the box.

Answer

No, the MVS needs to be mounted externally to the vacuum in a reference area or an area open to the atmosphere and connected to the vacuum source via appropriate process tubing depending on the model.
