Side-Mounted Level Switch with Spade Connector

Madison Company offers a standard liquid level side-mounted switch that has a 1/4" male spade connector for simplified electrical installation. The mounting is a 1/2" NPT thread for a vessel wall through hole. Both design features provide for easy field maintenance.

The M7725 is constructed of PBT (Polybutylene Terephthalate) with an operating temperature up to 130°C for most hydrocarbon liquids. PBT should not be used in water over 65°C. The M8725 is all polypropylene, for general-purpose applications and those involving highly acidic liquids. Its operating temperature should not exceed 105°C.

The M8750 and M8755 (not shown) are similar to the M8725 but come with 24” 22 ga. MTW wire leads. All models are UL, CSA, CE and NSF approved.

Madison Company also offers designs engineered specifically for unique application needs.
