An electro-mechanical liquid level float switch that continuously actuates a switch on sensing a change in the liquid upon reaching a threshold level, where the float-switch requires manual reset once the switch has been actuated. The float switch has an elongated stem with a reed switch embedded in one end of the stem, and a float with a magnetic portion. The float is constrained to move between a stop below the switch and an upper stop above the switch. When the float is abutted against the upper stop, it is aligned with the switch. Once aligned with the switch, the switch is actuated. The float is held is alignment with the switch by a magnet located in the upper stop, where the magnet can support the weight of the float. Once the switch is actuated it remains actuated, unless the float is physically separated from the magnet.
