Description
This Square Silicone Button PWM Controller is a satisfyingly squishy, easy-to-wire PWM output button controller with three color power-adjustment statuses in red, blue, and green. It provides a simple way to add a three-cycle power/PWM button and a colorful universal power symbol to your project.
Originally designed for controlling heating pad modules in wearable thermal vests, it can be hacked for various DIY projects. Note this is a three-cycle button, not an on-off switch! The internal LED is independent and serves as an indicator only.
The red and black wires are the power input (3.6~12VDC, red positive, black ground). The blue wire is the output power with a 'common anode' configuration (it grounds the pin to pull power from the positive supply).
Usage:
- Press and hold for 2 seconds to turn on at 100% PWM (red light).
- Press again for 70% PWM (blue light).
- Press again for 35% PWM (green light).
- Long press 2 seconds to turn off.
Note: The PWM duty cycle takes a few seconds to change; suitable for Peltiers, heaters, and fans where rapid on/off cycling is acceptable.
Technical Details:
- Voltage: 3.7 to 12V
- Current: 0 to 2.0A
- Waterproof rating: IP67
- Wires: ~80mm 24AWG
