The **ALTG-B13-R** is a specific model of an **Illuminated Tactile Switch** (Push Button) commonly used in consumer electronics, industrial controls, and PC peripherals. It is known for its compact profile and integrated LED. --- ### 1. Key Technical Specifications The following table highlights the typical electrical and mechanical characteristics for this series: | Parameter | Specification | | :--- | :--- | | **Switch Type** | Momentary Tactile Switch | | **Mounting Type** | Through-hole (THT) or Surface Mount (SMD) | | **Contact Rating** | 50mA @ 12V DC | | **Contact Resistance** | 100 mΩ Max | | **Insulation Resistance** | 100 MΩ Min @ 100V DC | | **Operating Force** | 160gf ± 50gf (Standard) | | **Travel Distance** | 0.25mm ± 0.1mm | | **Illumination** | Integrated LED (Red/Green/Blue/Bi-color options) | | **Operating Life** | 100,000 to 500,000 cycles | --- ### 2. Component Structure The ALTG-B13-R consists of several internal electronic and mechanical layers: * **Actuator:** The top button part that the user presses. * **Contact Dome:** A stainless steel or copper alloy disc that provides the "click" feel and completes the electrical circuit when compressed. * **Integrated LED:** Unlike standard switches, the LED is built directly into the housing, saving PCB space and ensuring the light is centered under the button cap. * **Terminals:** Usually 4 or 6 pins. Two pins are for the switch circuit (SPST), and the others are dedicated to the LED (Anode and Cathode). --- ### 3. Pinout Logic While specific layouts can vary by manufacturer (often associated with brands like *Highly* or *Salecom* style clones), the general pin configuration follows this logic: ```text Pin 1 & 2: Switch Contacts (Normally Open) Pin 3: LED Anode (+) Pin 4: LED Cathode (-) ``` --- ### 4. Typical Applications * **Control Panels:** Reset buttons or mode selection. * **Audio Gear:** Mute buttons or channel selectors with visual feedback. * **Medical Devices:** Compact interfaces requiring tactile confirmation. * **Computer Peripherals:** Custom mechanical keyboards or macro pads.
