The miniature float switches of the MR1K series are designed for applications with extremely limited installation space. The 8 mm switch tube enables precise and reliable level detection despite compact dimensions. The reed technology operates without continuous current and offers durable, interference-free limit level detection. Installation via an internal G 1/8 thread ensures a secure, pressure-resistant, and clean setup in tanks and small systems.
