YL-99 Impact Switch Module

The YL-99 Impact Switch Module is a compact and reliable sensor module designed to detect physical impact, vibration, or mechanical switch press using a built-in microswitch. It features a lever-type tactile switch that changes the logic output from HIGH to LOW when pressed, with a visible onboard LED indicator lighting up during the activation.

This module is ideal for basic sensing applications with Arduino and other microcontrollers where physical state change detection is needed. It includes a 10K pull-up resistor to keep the output logic HIGH by default, and the module operates safely on standard logic levels (3.3V or 5V).
