The **KADS-K0-R** is an industrial-grade illuminated pushbutton switch, typically manufactured by companies like **Kacon**. These components are widely used in control panels, automation systems, and machinery interfaces. Below is a detailed breakdown of its electronic and mechanical parts. --- ### 1. Technical Specifications Table | Feature | Description | | :--- | :--- | | **Component Type** | Illuminated Pushbutton Switch | | **Mounting Diameter** | 16mm (Round type) | | **Action Type** | Momentary (Spring Return) or Maintained (Latch) | | **Contact Configuration** | 1NO (Normally Open) + 1NC (Normally Closed) | | **Contact Rating** | 3A at 250VAC / 5A at 125VAC | | **Illumination Source** | LED or Incandescent Bulb | | **Protection Rating** | IP40 / IP65 (Depending on the specific sealing) | --- ### 2. Core Electronic & Mechanical Parts The KADS-K0-R is a modular assembly consisting of the following primary sections: #### A. The Operator (Head Unit) * **Actuator:** The round red button ("R" in the part number usually signifies **Red**). * **Lens:** A translucent plastic cover that diffuses the light from the internal lamp. * **Bezel:** The outer ring that holds the button in place against the control panel. #### B. The Contact Block This is the electrical heart of the switch. It usually features: * **Silver Contacts:** High-conductivity points that open or close the circuit. * **Terminals:** Solder or quick-connect pins (usually 5 pins: 2 for the lamp, 3 for the switch contacts). * **Switching Logic:** * **NO (Normally Open):** Circuit is broken until the button is pressed. * **NC (Normally Closed):** Circuit is continuous until the button is pressed. #### C. The Illumination Module * **LED/Lamp:** Located in the center of the unit. * **Voltage Resistor:** Often built-in to allow the LED to operate at specific voltages (e.g., 12V, 24V, or 110/220V). * **Lamp Terminals:** Separated from the switch contacts to allow the light to be controlled independently (e.g., the light stays on even when the button isn't pressed). --- ### 3. Wiring Diagram (Terminal Pinout) Most KADS series switches use a standard 5-pin layout: ```text Pin 1: Common (C) Pin 2: Normally Closed (NC) Pin 3: Normally Open (NO) Pin 4: Lamp Terminal (+) Pin 5: Lamp Terminal (-) ``` --- ### 4. Application Use-Cases * **Emergency Indicators:** Using the red illumination to signal a fault or stop condition. * **User Interface:** Providing tactile feedback to an operator in a factory setting. * **Low Current Signaling:** Interfacing with PLCs (Programmable Logic Controllers) to trigger logic sequences.
