The **KSP-22-R/DN** is a specific model of a **Miniature Slide Switch**, commonly used in electronics for power control, signal routing, or mode selection. --- ### 1. Technical Specifications Below are the typical electronic characteristics for the KSP-22 series: | Parameter | Specification | | :--- | :--- | | **Circuit Configuration** | DPDT (Double Pole Double Throw) | | **Switching Positions** | 2 positions (On-On) | | **Current Rating** | 0.3A at 30V DC (Typical) | | **Contact Resistance** | ≤ 30mΩ (Initial) | | **Insulation Resistance** | ≥ 100MΩ at 500V DC | | **Dielectric Strength** | 500V AC for 1 minute | | **Mechanical Life** | 10,000 cycles minimum | --- ### 2. Breakdown of the Model Name While nomenclature can vary slightly by manufacturer (e.g., Kingley or other generic brands), the code usually breaks down as follows: * **KSP:** Series designation (Miniature Slide Switch). * **22:** Refers to the internal circuit structure—**2 Poles, 2 Throws (DPDT)**. * **R:** Often indicates a **Right-Angle** mounting orientation (pins are bent at 90 degrees to the body). * **DN:** Usually refers to the **PCB Through-Hole** mounting type or a specific knob height/material variation. --- ### 3. Pin Configuration and Circuitry The DPDT configuration means the switch has **6 pins** in total. It operates as two separate switches controlled by a single physical slider: ```text Position 1: Position 2: (1)--[2] (4)--[5] [1]--(2) [4]--(5) (3) (6) (3) (6) ``` * **Common Pins:** Pin 2 and Pin 5. * **Operation:** In Position 1, Pin 2 connects to Pin 1. In Position 2, Pin 2 connects to Pin 3. The second pole (Pins 4, 5, 6) operates identically and simultaneously. --- ### 4. Common Applications * **Small Appliances:** Power ON/OFF switches for battery-operated devices. * **Audio/Video:** Selecting between different input sources or output modes. * **DIY Electronics:** Used on breadboards or custom PCBs for logic level switching (High/Low). * **Computer Peripherals:** Configuration switches for hardware settings. ---
