Simple theory as liquid buoyancy is utilized for the main principle of this "FF" series. A change of liquid level correspondingly travels the float to extreme levels up and down. The reed switch is thus "NC" and "NO" exchanged as well as the permanent magnet on pivot will have mutual repellence to the other one inside on the housing for like poles, which the Microswitch is button-pushed by magnet to states "NO" and "NC" exchanging likewise.

• Both MicroSwitch type and Reed Switch are available.
• The MicroSwitch type is usable even at ambient temp. of 100'C max.
• Mounting flanges are custom-specifiable. (JIS, DIN, ANSI).
• A rich variety of floats can be suited different specific gravity (S.G.) of liquid.(Custom-made)
• Liquid-wetted party material can be selected for SUS304 or SUS316 as well as enclosure explosion proof model.
