The **48AV-2RVH-R** is a specific part number typically associated with **Tactile Switches** (also known as tact switches). These are small electromechanical switches used to provide a physical "click" or tactile feedback when pressed. Below is a breakdown of the electronic specifications and characteristics generally associated with this component series. --- ### 1. General Specifications Tactile switches like the 48AV series are designed for low-power signal switching. They are momentary switches, meaning they only complete the circuit while being held down. | Feature | Specification (Typical) | | :--- | :--- | | **Switch Type** | Tactile Switch (Momentary) | | **Contact Material** | Silver Plated (Standard) | | **Current Rating** | 50mA @ 12VDC | | **Dielectric Strength** | 250V AC for 1 minute | | **Insulation Resistance** | 100 MΩ minimum | | **Operating Temperature** | -25°C to +70°C | --- ### 2. Part Number Breakdown (Nomenclature) The suffix codes determine the physical orientation and mounting style of the switch: * **48AV**: The base series designation (Standard Tactile). * **2R**: Refers to the **Actuation Force** (often 160gf or 260gf depending on the manufacturer's specific catalog). * **V**: Often denotes **Vertical** or **Right Angle** mounting configuration. * **H**: Usually indicates the **Height** of the actuator (the button stem). * **-R**: Typically signifies **RoHS Compliance** or **Tape and Reel** packaging. --- ### 3. Physical Configuration The "V" and "H" designations are critical for PCB design. This part is commonly used in applications requiring a **Right-Angle (Vertical)** mount, where the button faces out the side of the device rather than the top. * **Mounting Type:** Through-hole or Surface Mount (depending on the specific lead shape). * **Feedback:** Provides a crisp, audible click. * **Durability:** Usually rated for 100,000 to 1,000,000 cycles. --- ### 4. Common Applications Due to its small footprint and reliability, this part is found in: 1. **Consumer Electronics:** Volume buttons, power buttons on cameras, or handheld devices. 2. **Industrial Controls:** Reset switches on PCB boards. 3. **Computing:** Peripheral input buttons and network router reset pins. 4. **Automotive:** Dashboard controls and key fobs. ---
