- FLUID IO Mercury-free float switch with µ-switch
Product description
These float switches are characterised by their switching system which works without mercury. The switching system consists of a µ-switch which is operated by a ball and which switches with an angle of approx. +3° / +12° ( without hysteresis) and with an angle of approx. (with –26° / +28° additional hysteresis).
