The **K14-R** refers to a specific series of high-quality **industrial pushbutton switches** and indicators manufactured by **EAO**. These components are widely used in machinery, medical equipment, and control panels due to their modular design and durability. --- ### 1. Key Electronic Components The K14-R series is modular, meaning it consists of several interchangeable parts that form the complete electronic assembly: | Component | Description | Function | | :--- | :--- | :--- | | **Actuator** | The physical button (flush or raised). | Interface for user input. | | **Switching Element** | The internal contact block. | Opens/closes the electrical circuit. | | **Illumination** | LED or Incandescent lamp. | Provides visual feedback/status. | | **Mounting Flange** | The structural housing. | Secures the part to the panel. | --- ### 2. Technical Specifications The electronics of the K14-R are designed for low to medium power applications, often found in PLC (Programmable Logic Controller) circuits. * **Contact Material:** Typically Gold (for low currents) or Silver (for standard power). * **Switching System:** Snap-action switching element with double-break contacts. * **Illumination Voltage:** Options usually include 6V, 12V, 24V, or 48V (AC/DC). * **Terminals:** Plug-in terminals or soldered connections. --- ### 3. Wiring and Circuitry The K14-R can be configured in various electronic states depending on the contact block chosen: 1. **Normally Open (NO):** The circuit is completed only when the button is pressed. 2. **Normally Closed (NC):** The circuit is broken when the button is pressed. 3. **Momentary Action:** Returns to the original state immediately after release. 4. **Maintained (Latching) Action:** Stays in the new state until pressed again. --- ### 4. Typical Applications Because of its high IP rating (usually IP67 for the front) and electronic reliability, it is found in: * Public transportation control desks. * Lifting and moving machinery. * Industrial automation panels. * Medical diagnostic equipment.
