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.\n\nOriginally 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).\n\nKey Features\n\n\nThree Power Levels – 100% (red), 70% (blue), and 35% (green) PWM duty cycle\n\nInput Voltage – 3.6V to 12VDC\n\nWiring – 3-wire: red/black (power input), blue/black (PWM output, shared ground)\n\nIlluminated Button – Built-in power symbol LED indicates current level\n\nLong Press Control – Hold 2 seconds to turn on/off\n\nSilicone Housing – Soft, tactile button with satisfying press feel\n\n\n\nNote: 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.\n\n\nIdeal For\n\nWearable heating pad and thermal vest projects\nFan speed control\nPeltier module power management\nDIY projects needing simple adjustable DC power\n\n\nPackage Contents\n\n1× Square Silicone Button PWM Controller\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2185,"title":"Default Title","sku":"AF-5436","price":5.41,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
