    You basically get 3 type of switches. The brackets they mount against do differ.

    The one type is the white float ring around "pillar" with sensor inside pillar part

    Another type works like a toilet float, with swing arm

    Latest designs works with sensor that measures the distance to the water. so no real contact between switch and water.

    and do not use the 220V types. If something goes wrong, 12V chocks a lot less than 220V.

    That's only relevant if you not using 220V, but do use 12V dc its safer
