On/Off Self-Lock 12mm 2pin - Green
On/Off Self-Lock Push Button – 12mm, 2-Pin (Green)
Overview:
This 12mm self-locking push button switch (also known as a latching switch) is a compact and reliable component ideal for toggling power or modes in your electronic projects. Press once to lock ON, press again to release OFF — perfect for power toggles, mode selectors, and control panels.
With a bright green actuator, this button offers excellent visibility and tactile feedback. It features a durable 2-pin design, making it easy to use with Arduino, ESP32, Raspberry Pi, or any low-voltage control circuit.
Key Features:
Action Type: Self-locking (latching)
Function: Press to toggle ON → press again to OFF
Pins: 2 (Normally Open, latching)
Button Color: Green
Mounting Hole: Fits 12mm diameter
Panel mount design with plastic threaded ring
Durable, compact, and easy to install
Ideal for low-voltage DC projects (up to 12V)
