Reliable industrial control component
We use these in our junior robotics kits. They have held up well under frequent student use. The voltage range is flexible enough for both 3.3V and 5V logic systems.

Solid performer
Does exactly what it says on the tin. The response time is immediate. I wish the PCB had silkscreen labels for the pins, but the pinout is standard enough to figure out quickly.

Great for learning embedded systems
Bought this for my university microcontroller course. It makes testing interrupt handlers very easy. The LED indicator is a nice touch to confirm power status instantly.

Good quality, compact size
The board is well-made with solid soldering. It fits perfectly into tight spaces on my custom enclosure. Only giving 4 stars because the included headers were slightly bent, but easy to straighten.

Perfect for Arduino projects
This module works flawlessly with my Arduino Uno. The tactile feel of the button is crisp, and the output signal is clean without any bounce issues that I could detect. Great for quick prototyping.

Excellent value for money
For the price, you cannot beat the quality. I ordered five of them for a home automation panel, and all arrived in perfect condition. Highly recommended for DIY enthusiasts.
Q: Are the mounting holes standardized for M3 screws?
A: Yes, the four corner mounting holes are drilled to fit standard M3 screws, allowing for easy installation in enclosures or on DIN rails with appropriate adapters.
Q: Does the output require an external pull-up or pull-down resistor?
A: No, the board includes onboard resistors configured for standard operation. You can connect the output pin directly to your microcontroller's GPIO.
Q: Can I daisy-chain multiple modules together?
A: While there is no specific daisy-chain header, you can easily wire multiple modules in parallel to a single input pin if you need multiple trigger points for the same signal.
Q: Is this module compatible with 3.3V logic boards like the ESP32?
A: Yes, this module operates comfortably within the 3.3V to 5V DC range, making it fully compatible with ESP32, ESP8266, and 3.3V Arduino variants.
Q: What is the current rating of the tactile switch?
A: The tactile switch is rated for typical signal-level currents (up to 50mA). It is designed for logic control signals, not for switching high-power loads directly.
