Float Switch — Model EP2508 (Made in CHINA) Why choose this float switch Reliable lowcurrent level sensing: designed to detect water level changes and provide a simple on/off signal for control circuits. Compact, lightweight, and durable: polypropylene (PP) construction resists corrosion and delivers long service in common water applications. Easy to mount and integrate: M8 thread and 36 mm (1.4') total length fit small tanks, fittings, and DIY assemblies. Key features and specifications Model: EP2508 Function: Water level float switch / water level sensor Country of manufacture: CHINA Material: Polypropylene (PP) Main color: White, Yellow Net weight: 7 g Total length: 36 mm / 1.4' Thread diameter: M8 Electrical limits: Max wattage: 10 W Max switch voltage: DC 100 V Max switch current: 0.5 A Max breakdown voltage: DC 220 V Max contactor resistance: 100 mΩ Operating temperature range: 10 to +85 °C Package contents: 1 x Water Level Sensor (EP2508) How this product solves common problems Prevents overflow or dryrun: sends a reliable on/off signal when water reaches a set level so pumps or alarms can be controlled. Simplifies lowpower control: small form factor and low contact resistance provide a clean switch input for microcontrollers, relays, and monitoring electronics. Fits tight spaces: compact length and M8 thread allow installation where larger sensors won't fit. Compatibility and safe use notes Intended for lowvoltage DC and lowcurrent control circuits. With max switch current 0.5 A and max wattage 10 W, use external relays or drivers when controlling higherpower devices. Polypropylene body offers good chemical resistance for fresh water and many common fluids, but verify compatibility for aggressive chemicals. Observe the specified voltage and temperature limits for safe, longterm operation. Typical applications Small tanks and reservoirs: automatic off or overflow protection for compact water storage. Aquarium and hydroponics: trigger controllers or alarms for waterlevel management (use a relay for pump control above rated current). Condensate, drip trays, or appliance monitoring: detect presence/absence of water in confined spaces and send signals to control electronics. What you get One EP2508 float switch, ready to mount via M8 thread. Lightweight (7 g) and compact for straightforward installation.
