The **M2XU-T10-R** is a specific model within the **Omron M2X series** of miniature illuminated pushbutton switches. These components are widely used in industrial control panels, communication equipment, and office automation. ### 1. General Specifications The electronic architecture of the M2XU-T10-R is designed for low-power signaling and status indication. | Feature | Specification | | :--- | :--- | | **Manufacturer** | Omron | | **Switch Type** | Pushbutton (Illuminated) | | **Action** | Momentary (Non-locking) | | **Contact Form** | SPST-NO (Single Pole Single Throw - Normally Open) | | **Illumination Color** | Red (Indicated by the "-R" suffix) | | **Operating Voltage** | Typically 5V to 24V DC (Model dependent) | | **Mounting Type** | PCB Mount (Through-hole) | --- ### 2. Key Electronic Components #### A. Internal LED (Light Emitting Diode) The "R" in the model number signifies a **Red LED**. * **Polarity:** The LED has a specific anode (+) and cathode (-) terminal. * **Resistor Requirement:** Depending on the specific sub-variant, these may require an external current-limiting resistor to prevent the LED from burning out if the supply voltage exceeds the LED's forward voltage (typically ~2.0V for Red). #### B. Contact Mechanism The electronic switching is handled by high-reliability contacts. * **Material:** Often gold-plated or silver-alloy to ensure low contact resistance and prevent oxidation. * **Rating:** These are "signal-level" switches, usually rated around **100mA at 30VDC**. They are not designed to switch high-power AC loads directly. #### C. Termination Pins The unit features four or more pins: 1. **Switch Terminals (2 pins):** Closes the circuit when the button is pressed. 2. **LED Terminals (2 pins):** Separately powered to allow the light to be controlled independently of the switch state (e.g., the light can stay on even when the button is not pressed). --- ### 3. Application Circuit Example When integrating this part into a microcontroller circuit (like an Arduino or PLC), the wiring usually follows this logic: ```cpp // Logic Diagram [VCC] --- [Resistor] --- [LED Anode pin] [GND] ------------------ [LED Cathode pin] [Input Pin] ------------ [Switch Pin 1] [GND] ------------------ [Switch Pin 2] (Using Internal Pull-up) ``` --- ### 4. Physical Dimensions * **Form Factor:** Miniature square or rectangular profile. * **Travel:** Short-stroke tactile feedback, providing a clear electronic "click" to the user.
