The **KCK-11-R** is a specific model of a **Miniature Horizontal Slide Switch**. These components are widely used in consumer electronics to control power states or toggle between different modes of operation. Below is a detailed breakdown of its electronic specifications and physical characteristics. --- ### 1. Key Technical Specifications The "R" suffix often denotes a "Right Angle" mounting configuration or a specific RoHS compliance rating depending on the manufacturer, but the core specs for the KCK-11 series are generally standardized. | Feature | Specification | | :--- | :--- | | **Switch Type** | Slide Switch | | **Circuit Configuration** | SPDT (Single Pole Double Throw) | | **Positions** | 2-Position (ON-ON or ON-OFF) | | **Current Rating** | 0.3A to 0.5A | | **Voltage Rating** | 50V DC | | **Contact Resistance** | $\le$ 30m$\Omega$ | | **Insulation Resistance** | $\ge$ 100M$\Omega$ at 500V DC | | **Dielectric Strength** | 500V AC for 1 minute | | **Actuator Length** | Usually 2mm to 5mm | --- ### 2. Physical Construction The KCK-11-R consists of several critical sub-components that ensure electrical connectivity: 1. **Terminal Pins:** Typically made of brass with silver or gold plating to prevent oxidation and ensure easy soldering to a PCB. 2. **Contact Plate:** A moving metal "slider" inside the housing that bridges the gap between the common pin and the active output pin. 3. **Housing/Casing:** Usually made of a high-temperature thermoplastic (like PBT or PA66) to withstand soldering heat. 4. **Actuator:** The plastic handle used by the operator to slide the switch. --- ### 3. Pinout and Circuitry As an **SPDT** switch, the KCK-11-R typically features **3 pins**: * **Pin 1:** Output A * **Pin 2 (Center):** Common (Input) * **Pin 3:** Output B When the slider is moved to one side, Pin 2 connects to Pin 1. When slid to the opposite side, Pin 2 connects to Pin 3. --- ### 4. Common Applications Due to its small footprint and low current handling, it is found in: * **Battery-powered toys:** For main power toggling. * **Flashlights:** Small LED torches. * **DIY Electronics:** Breadboard projects and small PCB prototypes. * **Audio Equipment:** Selecting between Mono/Stereo or Gain levels. ---
