The **ASR00030-R** is a specific electronic component, typically identified as a **tactile switch** (or tact switch) used in consumer electronics, industrial controls, and PC peripherals. It is known for its compact footprint and reliable mechanical feedback. --- ### 1. Technical Specifications Below are the typical electrical and mechanical parameters for the ASR00030-R series: | Parameter | Specification | | :--- | :--- | | **Component Type** | Tactile Switch (Push Button) | | **Mounting Type** | Surface Mount (SMD) / Right Angle | | **Contact Rating** | 50mA @ 12V DC (typical) | | **Operating Force** | 160gf to 250gf (depending on sub-model) | | **Travel Distance** | 0.25mm ± 0.1mm | | **Operating Life** | 50,000 to 100,000 cycles | | **Contact Resistance** | < 100mΩ | --- ### 2. Key Features * **Tactile Feedback:** Provides a distinct "click" sound and physical sensation when actuated, confirming the input to the user. * **Right-Angle Orientation:** The "R" in the suffix often denotes a **Right Angle** configuration. This means the button is pressed parallel to the PCB, making it ideal for side-mounted buttons on devices like smartphones or tablets. * **Compact Form Factor:** Designed for high-density PCB layouts where space is limited. * **Durability:** Built with high-temperature resistant materials to withstand reflow soldering processes. --- ### 3. Physical Construction The internal structure of the ASR00030-R consists of several layers: 1. **Actuator (Stem):** The part the user presses. 2. **Cover:** Usually metal, protecting the internal mechanism. 3. **Contact Dome:** A stainless steel or phosphor bronze disc that snaps down to complete the circuit. 4. **Base:** A heat-resistant plastic housing (LCP or Nylon). 5. **Terminals:** Silver or gold-plated leads for electrical connectivity. --- ### 4. Common Applications Due to its small size and right-angle actuation, it is commonly found in: * **Consumer Electronics:** Volume rockers or power buttons on cameras and handheld devices. * **Wearables:** Smartwatches and fitness trackers. * **Automotive:** Interior control panels and key fobs. * **Medical Equipment:** Portable diagnostic tools.
