The **MEPA-11PB-R** is a specific electronic component, typically categorized as a **Micro-Switch** or a **Tactile Push-Button Switch**. These components are widely used in consumer electronics and industrial control panels to provide user input signals. --- ### 1. Technical Specifications Below is a breakdown of the typical technical parameters for this series of switches: | Parameter | Description | | :--- | :--- | | **Component Type** | Momentary Push Button Switch | | **Mounting Type** | Through-Hole (PCB) | | **Circuit Configuration** | SPST (Single Pole Single Throw) | | **Contact Form** | Normally Open (NO) | | **Rated Voltage** | Typically 12V - 24V DC | | **Rated Current** | 50mA | | **Operating Force** | 160gf to 250gf (Common range) | | **RoHS Status** | Compliant (Indicated by the "R" suffix) | --- ### 2. Key Features and Construction The MEPA-11PB-R is designed for durability and tactile feedback. Its internal structure usually consists of: * **Actuator (Button):** The physical part pressed by the user. The "PB" often denotes a Push Button style. * **Contact Dome:** A metal dome that collapses when pressed, completing the circuit and providing a "click" feel. * **Terminals:** Metal pins (usually 4) that are soldered onto a Printed Circuit Board (PCB). * **Housing:** A heat-resistant plastic body that protects the internal mechanism. --- ### 3. Pinout and Circuit Representation Most switches in this category use a 4-pin layout where pins are internally connected in pairs. This provides mechanical stability on the PCB. ```text [ Pin 1 ]-------[ Pin 2 ] | | [--- Switch Gap ---] | | [ Pin 3 ]-------[ Pin 4 ] ``` *When the button is pressed, the connection between (1,2) and (3,4) is closed.* --- ### 4. Common Applications * **Computer Peripherals:** Reset buttons or power buttons. * **Consumer Electronics:** Microwave controls, TV buttons, and remote controls. * **Industrial:** Logic input for Microcontrollers (Arduino, ESP32) to trigger specific software routines.
