The **ALTG-414-R** is a specific electronic component typically identified as a **tactile switch** (or tact switch). These are momentary push-button switches commonly used in consumer electronics, automotive controls, and industrial interfaces. Below is a detailed breakdown of its specifications and electronic characteristics. --- ### 1. General Specifications The ALTG-414-R is designed for high-density mounting and features a small footprint. | Feature | Specification | | :--- | :--- | | **Type** | Tactile Switch (Momentary) | | **Mounting Style** | Surface Mount (SMD / SMT) | | **Circuitry** | SPST-NO (Single Pole Single Throw, Normally Open) | | **Operating Force** | Typically 1.6N to 2.5N (160gf - 250gf) | | **Actuator Height** | Specific to the "414" variant (often ~1.5mm to 2.5mm) | | **Contact Material** | Silver Plated (Standard) | --- ### 2. Electrical Characteristics These parts are designed for low-power signal switching rather than power distribution. * **Maximum Rating:** 50mA at 12V DC. * **Contact Resistance:** 100mΩ Max (Initial). * **Insulation Resistance:** 100MΩ Min at 100V DC. * **Dielectric Strength:** 250V AC for 1 minute. * **Bounce Time:** 10ms or less (Time taken for the signal to stabilize after pressing). --- ### 3. Physical & Environmental Attributes The suffix "-R" often denotes the packaging or a specific environmental compliance. * **Packaging:** Usually supplied in "Tape and Reel" (hence the **-R**) for automated pick-and-place assembly. * **Operating Temperature:** -25°C to +70°C. * **Durability:** Rated for approximately 50,000 to 100,000 cycles (depending on the specific manufacturer batch). * **Terminal Lead Style:** Gull-wing or J-bend SMT leads for soldering to a PCB. --- ### 4. Common Applications Due to its small size and tactile feedback ("click" feel), you will find the ALTG-414-R in: 1. **Consumer Electronics:** Remote controls, cameras, and handheld gaming devices. 2. **Computing:** Reset buttons or power buttons on motherboards and peripherals. 3. **Medical:** Control panels for portable diagnostic equipment. --- ### Summary Table: Pros and Cons | Pros | Cons | | :--- | :--- | | Excellent tactile feedback (audible click) | Not suitable for high-current switching | | Small SMD footprint saves PCB space | Sensitive to excessive heat during manual soldering | | Reliable for high-frequency low-voltage signals | Limited mechanical lifespan compared to industrial toggles |
