The L150 Series Level Swichgage instrument is a combination liquid level gauge and low limit switch; each unit includes a chamber with pivotal float, an indicating dial with pointer, and a low level contact. When properly installed and maintained, the float operates the pointer which, in turn, both indicates level during normal operation, and closes a switching circuit if the level falls to the low-limit set point.

The LM2000 maintains oil level on any size engine, as well as installations that require a 3-wire, snap-action switch.
