A single switch point liquid level probe, for use in water or aqueous liquids, designed to be suspended into the liquid by its cable. It can be configured to give make or break action on either rise or fall, by removing the protective shield and reversing the float orientation. The switching level may be adjusted by varying the cable length. The reedswitch contact is suitable for switching signal levels, up to 50 volts.

This is designed for use in non-turbulent water, with fairly constant ambient temperature, such as in indoor tanks or covered reservoirs. The switching element is a microswitch, having UL, VDE and CENELEC approvals, with either 10 or 20 Amp contacts, activated by a moving ball and having an electrical life of 200,000 operations.

This is suitable for open reservoirs and turbulent water and industrial wastewater. The switching element is self cleaning with 10 Amp contacts, and makes the complete switch insensitive to humidity and condensation, caused by wide temperature fluctuations. The switch is fitted with additional internal weight, such that it brings the centre of gravity and rotation close to the cable entry.

Suitable for use in water, industrial wastewater and sewage, that can have wide variations of temperature. This compact design of switch is for use in more confined spaces, where there is not enough room for the larger FFSMC type. The rounded body design and floating attitude prevents accumulation of solids on the body. The switch has additional internal ballast, to bring the centre of gravity and rotation close to the cable entry point.
