Vacuum Contact Switches

The Watteredge Vacuum Contact Switch provides a high current DC shorting switch which offers safety, reliability and long life. The switches provide superior performance in the harsh environments of electrolytic cell applications, particularly in chlor-alkali and metals refining processes.

Available in either fixed or portable models, every Watteredge switch is custom designed to accommodate specific customer needs.

Overall maintenance and energy costs are significantly reduced when patented Watteredge Vacuum Contact Switches are substituted for conventional contact switches. Further savings result from the elimination of lost production time due to emergency shutdowns or reductions in cell current caused by partial or complete failure of conventional contact switches.

Watteredge Vacuum Contact Modules provide a wide range of operating benefits, including:

• Longer life than any other configuration available
• Absence of contact corrosion, offering consistently low contact resistance
• No organic seals - the manufacturing process uses high-temperature brazed joints
• Elimination of entrapment of foreign material between the contacts
• Absence of exposed arcing and flying hot metal
• Operation at higher ambient temperatures without harm to contacts
• Increased facility productivity through near-elimination of downtime or reduced current operation due to faulty switches
