## Description

A squishy silicone button module with a built-in PWM controller and colour-changing power indicator. Press to cycle through three power levels — 100%, 70%, and 35% duty cycle — with the illuminated power symbol glowing red, blue, or green to show the current setting. Long press for two seconds to turn on or off. Originally designed for controlling heating pads in wearable thermal vests, this module is a simple way to add adjustable PWM power control to any DC project. It accepts 3.6–12VDC input and outputs the same voltage at the selected duty cycle via three wires (shared ground). Key Features Three Power Levels – 100% (red), 70% (blue), and 35% (green) PWM duty cycle Input Voltage – 3.6V to 12VDC Wiring – 3-wire: red/black (power input), blue/black (PWM output, shared ground) Illuminated Button – Built-in power symbol LED indicates current level Long Press Control – Hold 2 seconds to turn on/off Silicone Housing – Soft, tactile button with satisfying press feel Note: This is a three-cycle button, not an on/off switch. The internal LED indicator is independent and not connected to the switch output. The PWM duty cycle period is several seconds, so this works best for loads like heaters, Peltier modules, and fans where slow on/off cycling is acceptable. Ideal For Wearable heating pad and thermal vest projects Fan speed control Peltier module power management DIY projects needing simple adjustable DC power Package Contents 1× Square Silicone Button PWM Controller
