ON/OFF Switch 2 Pins 17x11mm
ON/OFF Rocker Switch – 2 Pins, 17×11mm
Overview:
This is a 2-pin SPST (Single Pole Single Throw) rocker switch used to control a single circuit — either ON or OFF. It's a simple and compact mechanical switch commonly used for power control in small appliances, DIY electronics, Arduino projects, and low-voltage DC circuits.
The switch is designed to mount securely in panels or enclosures and features a clear ON/OFF rocker action with a click sound for tactile feedback. It is rated for both DC and AC applications (within limits), and the compact 17mm × 11mm panel size makes it ideal for compact designs.

Pinout:
This 2-pin switch is extremely simple:
Pin 1 → Connect to input voltage (e.g., +VCC)
Pin 2 → Connect to output (e.g., to load or Arduino Vin)
When the switch is ON, it connects the two pins. When OFF, it opens the circuit.
Wiring Example – Power Control:
| Switch Pin | Connection |
|---|---|
| Pin 1 | Battery + or VCC line |
| Pin 2 | VIN or device power input (e.g., Arduino Vin) |
💡 Add a fuse for protection when controlling high-current loads.
Applications:
Main power switch for DIY projects
On/Off control for LED strips or modules
Power control in small appliances
General electronics projects (Arduino, ESP32, etc.)
Low-voltage DC system switching
