WIN MODDEN M15-2 Water Level Float Switch Liquid Controller (2M, 5M, 7M & 10M Cable Options) Automatic Sump Pump Switch High Reliability
The MODDEN Float Switch M15-2 Series (Order Code: M-HT-M15-2) provides an efficient, automatic liquid level control solution for water tanks, drainage sumps, sewage basins, and agricultural irrigation systems.
Engineered to automatically turn electric pumps on or off as water levels rise and fall, this switch prevents pump dry-running damage and prevents liquid overflow in containment tanks.
Designed with a high-durability molded float body and an adjustable counterweight block, the MODDEN M15-2 allows technicians to set high and low liquid switching thresholds. The internal switching mechanism utilizes micro-switch contacts housed inside a sealed casing to shield against moisture, dust, and liquid contamination.
To suit various installation depths and tank sizes, the MODDEN Switch series offers four standard factory cable lengths:
-
2-Meter Cable (Order Code: M-HT-M15-2-2M): Designed for compact water tanks, domestic sumps, and shallow basin applications.
-
5-Meter Cable (Order Code: M-HT-M15-2-5M): Standard option for residential overhead tanks, rainwater harvesting systems, and mid-depth sumps.
-
7-Meter Cable (Order Code: M-HT-M15-2-7M): Suitable for deep water storage reservoirs, commercial tanks, and drainage wells.
-
10-Meter Cable (Order Code: M-HT-M15-2-10M): Extended length for deep agricultural wells, large industrial holding tanks, and deep sump pits.
Whether applied to fill-control systems or drainage/de-watering pump setups, the MODDEN M15-2 Float Switch series delivers automated liquid level management across residential, commercial, and agricultural setups.

Frequently Asked Questions (FAQ)
Q1: How does the MODDEN M15-2 float switch control a water pump automatically?
A : The float switch contains an internal micro-switch and rolling steel ball. As the liquid level shifts, the float tilts, causing the ball to roll and activate or deactivate the internal electrical contact to start or stop the pump.
Q2: Can the MODDEN M15-2 float switch be used for both filling and emptying operations?
A : Yes, the switch features a 3-wire wiring setup that allows it to be wired for either filling mode (turns pump off when tank is full) or emptying mode (turns pump on when sump water rises).
Q3: What is the purpose of the red cylindrical counterweight included in the kit?
A : The red counterweight acts as a pivot point along the cable. By adjusting its position along the cable length, you can adjust the liquid level differential (switching distance) required to tilt the float.
Q4: Which cable length should I select for my water tank?
-
2M / 5M Cables: Ideal for shallow domestic water storage tanks, small sump pits, and home rainwater collection systems.
-
7M / 10M Cables: Recommended for deep commercial water tanks, agricultural wells, and deep underground drainage sumps.
Q5: Is the float switch body fully waterproof for continuous immersion?
A : Yes, the float body features a hermetically sealed enclosure designed for continuous immersion in non-corrosive liquids, clean water, and standard drainage sumps.
