The **YB215CWCKG01-24-JS** is a high-quality, illuminated pushbutton switch manufactured by **NKK Switches**. It belongs to the YB Series, specifically designed for panel-mount applications requiring durability and visual feedback. --- ### Technical Specifications The following table breaks down the electrical and mechanical characteristics of this specific part number: | Feature | Specification | | :--- | :--- | | **Circuit** | DPDT (Double Pole Double Throw) | | **Switch Function** | ON-ON (Maintained/Latching) | | **Current Rating** | 0.4VA Max @ 28V AC/DC (Logic Level) | | **Illumination Type** | LED (Bi-color or Single with Resistor) | | **LED Voltage** | 24V DC | | **Contact Material** | Gold (G) - Ideal for low-energy switching | | **Mounting Type** | Panel Mount, Threaded (16mm) | | **Ingress Protection** | IP65 (Dust tight, Water resistant) | | **Actuator Style** | Round, Flush | --- ### Part Number Breakdown Understanding the nomenclature helps identify the specific components of the switch: 1. **YB2**: Series identifier (YB Series Pushbutton). 2. **15**: Switch operation (DPDT, maintained). 3. **CW**: Environmental sealing (Splashproof/Dust tight). 4. **CK**: Mounting/Housing (Round, silver metallic bezel). 5. **G**: Contact material (Gold contacts for logic-level reliability). 6. **01**: Termination style (Solder lug). 7. **24**: LED Voltage (24 Volts). 8. **JS**: Cap/Diffuser color (Yellow/Silver/Clear combination). --- ### Key Electronic Features #### 1. Gold Contacts (Logic Level) Unlike silver contacts which require a "wiping" action to clear oxidation, gold contacts are designed for low-current applications (0.4VA max). They provide high reliability in digital circuits where the voltage and current are too low to arc. #### 2. DPDT Configuration The **Double Pole Double Throw** circuit allows you to control two separate electrical circuits simultaneously. This is useful for switching a signal while simultaneously triggering a status light or secondary logic gate. #### 3. Integrated 24V LED The "24" in the suffix indicates that the internal LED is designed to operate directly at 24V DC. It includes an internal resistor, meaning you do not need to calculate or solder an external current-limiting resistor if your supply is 24V. #### 4. IP65 Rating The "CW" designation indicates a "Cushion Work" or sealed construction. This provides an IP65 rating at the front panel, protecting the internal electronic contacts from moisture and debris. --- ### Typical Applications * Industrial control panels. * Medical instrumentation. * Communication equipment. * Testing and measurement devices.
