Technology
The vertical buoyancy switch and the vertical float switch both consist of a float, magnet, reed switch and baffle body which dampens
turbulence and eliminates the negative effects of switch chatter. When
the probe is dry, the float rests on the bottom of the baffle body such
that the magnet does not influence the reed switch. As the probe
becomes immersed in liquid, the float becomes buoyant and the magnet elevates causing the reed switch to change state.
