Square Silicone Button PWM Controller - 3 Wire - 3.6V to 12VDC
Squishy silicone push button that cycles a PWM output through three power levels (indicated by red, blue, and green LED states) on each press. Operates 3.6–12 VDC via three wires; originally designed for wearable heating pads.
Pinout
- RED
Positive power input wire. Source states red positive.
Type · PowerVoltage · 3.6V to 12VDC input - BLACK
Ground / negative power input wire. Source states black ground.
Type · GroundVoltage · 0V - BLUE
PWM-controlled output wire. Source describes common-anode behaviour where this wire is grounded/pulled low to draw power from the positive supply.
