Liquid Water level sensor Side Mounted Float Switch (liquid level side mounted)

The liquid level switch detects the rising level of liquid in a sump or tank. It can be connected to a micro controller. It can then be used to start/stop a pump which then pumps liquid in/out until the level of the liquid has been restored to the point where the pump is switched off again. The switch may be used in a pump station, a sensor, a tank alarm, or other devices.

Discontinued: Automatic Electric Water Bilge Pump Switch Sensor (AW bilge pump float switch)
Description:

Our bilge pump float switch is safer than mercury switches, this switch utilizes a mercury-free rolling ball mechanism and includes an exclusive anti-spike feature to prevent the rapid on/off cycling encountered with some switches. Made of rugged thermoplastic. Universal design works with all 12V, 24V and 32V bilge pumps.

A bilge pump float switch is a smart device used in boats that turns on a bilge pump when the water in the bilge reaches a certain level. It is a must-have in any boat that is left unattended for any length of time, as all boats tend to leak at least some water. This switch is submerged, so you need to waterproof the electrical connections and hang the wires to ensure they stay as dry as possible.
 
Features:
 
1. Turn pump on when water level reaches 2 (51mm).
2. Turn pump off when water level reaches 3/4 (19mm).
3. Ideal flow sensor for bilge pumps.
4. Heavy duty flow switch is designed for the toughest applications.
