INFICON Vacuum Switches are designed for accurate and reliable pressure detection.The pressure switch VSA100A is used as a safety switch in vacuum systems. For example, to automatically interrupt the gas supply when venting vacuum systems with a purge gas at a pressure of 6 mbar below atmospheric pressure.

At a differential pressure of 6 mbar resp. return switching pressure of 3 mbar below atmospheric pressure, an elastic diaphragm actuates a changeover contact which in turn may be used to switch directly any ancillary equipment. The electrical connections are protected by a plastic cover.. For complete use and specifications see .pdf's to the left at Downloads.

Key Features:
• Reliable and budget-priced vacuum switch.
• Long service life.
• Easy to integrate.
• IP 44 protection.
• Can be connected to a programmable control.
• Used as Pressure interlock (power supplies, gas supplies, pumps, valves, actuators, etc.
