The KCD11-101 Mini Rocker Switch is a compact, reliable 2-pin ON/OFF rocker switch designed for a variety of low-power electrical applications. With a maximum voltage rating of 250V AC and a current rating of 3A (or 6A at 125V AC depending on the source), it provides a simple SPST (Single Pole Single Throw) configuration for basic power control. Its small footprint, measuring 15x8.5x17.5mm, and a mounting hole size of 14x8.5mm make it ideal for space-constrained projects, including DIY electronics, household appliances, automotive controls, and industrial instruments. The switch features a durable plastic housing, often available in black, and is designed for panel mounting with a snap-in installation, ensuring ease of use and stability.
This switch operates effectively as a manual power toggle, suitable for controlling circuits in Arduino projects, small power supplies, or lighting systems. It includes two terminals for straightforward wiring, requiring connection to a power source and load. The module is rated for an operating temperature range of approximately -25°C to +85°C (based on similar KCD series switches), though specific environmental ratings may vary. With an IP20 rating, it offers basic protection against solid objects but is not waterproof, making it best suited for indoor use. For Arduino integration, connect one terminal to a power rail (e.g., 5V or 12V) and the other to a load or microcontroller pin, ensuring the current does not exceed 3A.
Note: Verify the voltage and current requirements of your application to avoid damage, and consider a fuse for added safety in high-power setups.
