Letzgo Bobber Sump Pump Water Level Sensor

Detects & Warns Of Sump Pump Failures

This simple sump pump float switch monitors the water level in your sump pump and lets you know if the water level rises or falls. Connect this sump pump water level sensor to a warning device or alarm system for a low cost sump pump alarm. The switch can also be connected to relays and other devices to drive high current loads.

• Monitors the water level in a sump pump well
• Connect to a warning device or alarm system
• Hose clamp allows easy level adjustment
• Easily configured as a normally open or normally closed switch

Offering high reliability, the bobber’s sealed reed switch provides high isolation when pump wiring breaks down. The sump pump float switch operates even when totally submerged and its stainless steel hose clamp allows easy level adjustment. Its unique reversible float allows for an N.O. or N.C. switch circuit. It fits virtually all sizes and types of return pipes, and comes complete with a stainless steel hose clamp and 20 lead wire.
