The **KUS-41-R** is an electronic component primarily classified as a **Slide Switch**. It is widely used in small consumer electronics, testing equipment, and industrial control panels due to its compact form factor and reliability. --- ### 1. General Specifications Below is a breakdown of the typical technical parameters for the KUS-41-R series: | Feature | Specification | | :--- | :--- | | **Switch Type** | Slide Switch | | **Circuit Configuration** | SPDT (Single Pole Double Throw) | | **Switch Function** | ON-ON | | **Mounting Type** | Through-hole (PCB Mount) | | **Current Rating** | ~0.3A at 30V DC | | **Contact Resistance** | ≤ 20mΩ | | **Insulation Resistance** | ≥ 100MΩ (500V DC) | | **Dielectric Strength** | 500V AC for 1 minute | --- ### 2. Key Electronic Parts and Materials The internal and external construction of the KUS-41-R consists of several critical layers: 1. **Actuator (The Knob):** Usually made of hardened POM (Polyoxymethylene) plastic. This is the part the user moves to change the switch state. 2. **Contact Clips:** These are the internal moving conductive elements. They are typically made of **Phosphor Bronze** with **Silver or Gold plating** to ensure high conductivity and prevent oxidation. 3. **Terminals:** The pins that solder into the PCB. These are usually brass with silver plating. 4. **Base/Housing:** Constructed from high-temperature resistant Phenolic resin or PA (Nylon) to withstand soldering temperatures. --- ### 3. Circuit Configuration (SPDT) The KUS-41-R operates as a Single Pole Double Throw switch. Here is a simple representation of its logic: ```text [ Terminal 1 ] <--- Position A [ Common Terminal ] [ Terminal 2 ] <--- Position B ``` * When the slider is in **Position A**, the Common terminal is connected to Terminal 1. * When the slider is shifted to **Position B**, the Common terminal is connected to Terminal 2. --- ### 4. Applications Because of its small footprint and low power rating, you will find this component in: * **Handheld Devices:** Power switches for small toys or flashlights. * **Instrumentation:** Channel selectors or mode toggles. * **Computer Peripherals:** DPI switches on mice or wireless on/off toggles.
