ABOUT SWITCH-TEK™ MINI-FLOAT LEVEL SWITCH
The Mini-Float level switch consists of a float, magnet, reed switch and body/stem with mounting threads.
When the probe is dry, the float rests on the bottom of the stem 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.
