added to my tracker 170 - this was compact enough to fit in the very small area near the pump. Good quality wire and seems solid so hopefully will last awhile

Very solid operation and well built. I expect it to last a long time. Easy to separate for maintenance.

I opted for another Rule bilge pump switch for my DIY backup sump pump system. This new switch will replace the one I had which was still working but had aged out. The switch is well put together, feels solid and is compatible with the side mount fitting (for Rule pumps) that came with the previous switch.
