Product Title: Side-Mounted Small Plastic Float Level Control Switch (55mm)

Product Short Description: Reliably detect high or low liquid levels in tanks, reservoirs, and aquariums with this Side-Mounted Plastic Float Switch. Featuring a compact 55mm design, this mechanical switch utilizes a magnetic reed mechanism to complete or break a circuit when water levels change. It is an essential, easy-to-use component for automated water management and IoT liquid sensing projects.

Detailed Description: This side-mounted float switch is a simple yet highly effective liquid level controller. Unlike top-mounted sensors, this device is designed to be installed through the side wall of a tank or container. It features a hinged float that rises or falls with the liquid level. Inside the hinge is a magnet, and inside the fixed body is a sealed reed switch. As the float moves, it magnetically triggers the switch.

One of the best features of this sensor is its reversible operation: by simply rotating the switch 180 degrees during installation, you can configure it to act as either a Normally Open (N/O) or Normally Closed (N/C) switch. This makes it incredibly versatile for either triggering a pump when a tank is empty, or shutting off a valve when a tank is full.

Because it operates as a basic mechanical switch, reading its state requires no complex code. It connects effortlessly to the digital input pins of an Arduino Uno, ESP32, STM32 Blue Pill, or STM32 Black Pill with just a standard pull-up resistor. Whether you are assembling digital design and IoT hardware kits for environmental monitoring or building a custom hydroponic auto-filler, this float switch provides dependable, low-voltage level sensing.

Key Features:

• Reversible Action: Can be installed to trigger on rising fluid (high level) or falling fluid (low level) by rotating the unit 180 degrees.

• Side-Mount Design: Perfect for tanks where top access is restricted or impossible.

• Simple Integration: Acts as a standard mechanical switch; no special libraries or complex ADCs required.

• Compact Footprint: The 55mm size is unobtrusive and fits easily into small reservoirs or DIY enclosures.

Technical Specifications:

• Switching Power: Max 10W

• Switching Voltage: Max 110V DC

• Size/Length: 55mm float mechanism
