Why it matters
The VS-100 arrives assembled and clamps to the discharge pipe. PumpSpy rates it for up to one million on-off cycles, and its gold-plated contacts resist pitting; materials are chosen to reduce buildup so the float doesn't stick.
It's rated 10 A at 120 VAC and plugs in piggyback style, so it works with most sump, sewage and effluent pumps.
Who it's for, and who should skip it
Good fit if
- Narrow pits
- Replacing a stuck float
- Frequent cycling
Look elsewhere if
- Pumps over 10 A
- Wide sewage basins
Pros and cons
Pros
- Million-cycle rating
- Gold contacts
- Preassembled
Cons
- 10 A maximum
- Fixed range
- Clamping needed
Limitations to weigh
- Check the switch's amp and horsepower rating against your pump's nameplate before plugging it in.
- Piggyback switches plug into the outlet and the pump plugs into them; set the pump's own switch to manual or remove it, per the pump maker.
