Product Description

YL-99 Impact Switch Module

• The module mounts a small microswitch with a lever.
• The output is normally held HIGH via a 10K pull-up resistor on the module. When the switch lever is depressed, the output is pulled to ground and goes LOW and the LED on the module lights.
• The switch body is rated for up to 2A @ 125VAC, but the module is designed to switch logic level signals.

Module Connections

• 1×3 Header
• OUT = Output is normally HIGH. The output goes LOW when switch is depressed
• VCC = Power. Typically kept at 3.3 or 5V to match the uC it is used with
• GND = Ground which should be common with the uC.
• The module has one M3 hole for mounting.
