Great value for money
I bought five of these for a school project. All of them worked flawlessly out of the box. The pinout is clearly labeled which saves time.

Good quality, slightly bulky
The sensor is reliable and the build quality is solid. It is a bit taller than some other modules, so check your case dimensions before installing.

Sturdy construction
The PCB looks clean and the soldering points are well-made. The button click feels satisfying and durable. Will buy more for future projects.

Perfect for Arduino prototypes
This module works exactly as described. The self-locking mechanism is smooth and stays in place until pressed again. Easy to wire up with standard jumper cables.

Reliable switching action
Unlike momentary switches, this one holds the state perfectly. Ideal for toggle functions in my robot control panel. Highly recommended.

Easy to use for beginners
As someone new to electronics, I found this very easy to integrate. Just connect power and signal, and it reads high or low depending on the state.
Q: Can this be used with a 3.3V microcontroller?
A: Yes, the module operates comfortably within the 3.3V to 5V range, making it compatible with both 5V Arduinos and 3.3V boards like the ESP32.
Q: What is the difference between this and a momentary switch module?
A: This is a self-locking switch, meaning it stays in the ON or OFF position after being pressed. A momentary switch only activates while you are holding it down.
Q: Is a library required to use this sensor?
A: No library is needed. You can read the state simply by using the standard digitalRead() function in your Arduino sketch.
Q: Does this module require an external pull-up resistor?
A: Most Arduino boards have internal pull-up resistors that can be enabled in the code. However, if your specific setup requires it, you can easily add an external one.
Q: Are the mounting holes standard size?
A: Yes, the mounting holes are standard 3mm diameter, compatible with most M3 screws and standoff kits used in electronics projects.
