The **KSP-11-R** is a specific model of a **Miniature Rocker Switch**. These components are widely used in consumer electronics, power strips, and small appliances to control the flow of electricity. Below is a breakdown of its electronic specifications and physical characteristics. ### 1. Technical Specifications The KSP-11-R is defined by its electrical ratings and contact configuration. | Feature | Specification | | :--- | :--- | | **Circuitry** | SPST (Single Pole Single Throw) | | **Switch Function** | ON-OFF | | **Current Rating** | 3A 250V AC / 6A 125V AC | | **Contact Resistance** | ≤ 50mΩ (Initial) | | **Insulation Resistance** | ≥ 100MΩ (500V DC) | | **Dielectric Strength** | 1500V AC / 1 minute | | **Operating Life** | ~10,000 Cycles | --- ### 2. Physical Design & Parts The switch is composed of several key electronic and mechanical parts: * **Actuator (The Rocker):** The red plastic part (indicated by the "R" in the model name) that the user presses. It pivots to open or close the circuit. * **Terminals:** Two metal pins at the bottom. Since it is an **SPST** switch, one terminal is for the "Line" (input) and the other is for the "Load" (output). * **Contact Points:** Internal silver-plated alloy points that physically touch to complete the circuit. * **Housing:** A heat-resistant plastic body (usually Nylon 66) designed to snap-fit into a rectangular panel cutout. --- ### 3. Connection Diagram In an electronic circuit, the KSP-11-R acts as a break in the "Hot" or "Positive" wire. ```text [Power Source] ----(+)---- [Terminal 1] [ KSP-11-R ] [Load/Device] ----(+)---- [Terminal 2] [Power Source] ----(-)-------------------- [Load/Device] ``` --- ### 4. Key Applications * **Power Supplies:** Used as a primary power toggle. * **Small Appliances:** Fans, lamps, or kitchen electronics. * **DIY Projects:** Mounting on project boxes to control battery power to microcontrollers (like Arduino or ESP32). ---
