Typical application is to signal a "below normal" water level such as in a hot oven or cooler. When the water level drops below the sensing probe, an alarm or pilot light is activated. By raising the water level to the probe, the switch automatically de-activates the alarm or pilot light.
The switch is operated by establishing a conductive path between the probe and ground or neutral (1 megohm or less). The contact to ground electronically operates a triac output. The switch will be "off" when the non-insulated section of the probe is in the water, and will actuate when water is absent.

Probe metal parts are stainless steel. The conductor is teflon covered. Care must be taken to minimize distributed capacity between the probe and ground. Do not run probe lead in wire duct and, where possible, keep the probe away from surrounding metal objects.
