Johnson AS888 Automatic Bilge Switch - Johnson Pump

easy to install, and works very well

Easy to mount and even easier to connect. This switch works flawlessly and I would recommend this product to anyone looking for a dependable switch.

Simple in design and function and worked wonderfully with my bilge pump (brand unknown). Wish it was slightly smaller, so it was easier to mount, but I found a place it would work. Good price and does the job.

Switch works fine, but it's size did not allow proper mounting. Time will tell how long it lasts.

This switch has a simple rolling ball mechanism that works reliably. The instructions about placement and connection are easy to understand. It does not have to be used only with a Johnson pump. I hooked to a Rule pump with no problem. Don't waste your money on higher priced models that won't function any better. This switch does the job.
