The M3769 Interstitial Switch is a thin profile device designed for double-wall tanks and pipes. The 3/8" high switch is ideal for underground tanks and piping where the double-wall construction needs to be monitored for product release from the inner tank. It can also be used to signal the presence of liquid leaks or overflows in any containment area by connecting to a suitable alarm indicator. The avoidance of potential cleanup costs through early detection of leaks is well worth the cost of this unit.

The unit is constructed of a Valox 420 housing and Buna-N float with a stainless steel pivot pin. The standard model comes with 10' of Halar-jacketed cable.
