Hermetic Stainless Steel Pressure Switches

The Klixon® 6PS and 7PS series precision pressure switches are snap–acting, all–welded devices with hermetically sealed switch contacts. Our pressure switches were developed for applications in aerospace and electronics where high reliability and/or resistance to severe environments is required. To ensure maximum corrosion resistance under hostile conditions, all parts exposed to the pressure media and the environment are made of brass or 300 series stainless steel — no rubber parts are used.
Small and lightweight, 6PS and 7PS Series switches can be mounted by their pressure ports alone, allowing maximum flexibility of design.
Full contact force is maintained even during high shock and vibration—regardless of applied pressure—because the positive, snap–action disc works in tandem with snap–action switch contacts.
There are over 1,000 existing 6PS switch package designs. The 6PS is ideal for highly customized package and performance needs.
The 7PS is ideal for higher volume standard solution needs.
