## Technical Overview: YB215CWCKG01-12-JB The **YB215CWCKG01-12-JB** is a high-quality, illuminated push-button switch manufactured by **NKK Switches**. It belongs to the YB Series, known for its modular design and reliability in panel-mount applications. ### 1. Key Component Breakdown The part number can be decoded into the following technical specifications: | Feature | Specification | Description | |:---|:---|:---| | **Series** | YB Series | Standard size push-button switches. | | **Circuit** | DPDT | Double Pole Double Throw (On-On). | | **Action** | Alternate | Latching action (Push to lock, push again to release). | | **Bushing** | 16mm | Circular, panel-mount diameter. | | **Contacts** | Gold | Rated for low-level (logic) circuits. | | **Illumination** | LED | 12V DC integrated LED. | | **Cap Type** | Sculptured | Rectangular cap with a "Clear/White" filter and clear lens. | --- ### 2. Electrical Specifications This switch is specifically designed for low-power electronic signals rather than high-current power switching. * **Maximum Rating:** 0.4VA maximum @ 28V AC/DC maximum. * **Contact Resistance:** 50 milliohms maximum. * **Insulation Resistance:** 200 megohms minimum @ 500V DC. * **Dielectric Strength:** 1,000V AC minimum between contacts for 1 minute. * **LED Voltage:** 12V DC (Requires no external resistor for 12V operation). --- ### 3. Mechanical & Environmental Features ```yaml Mechanical_Life: 1,000,000 operations minimum Electrical_Life: 100,000 operations minimum Operating_Force: 1.5 Newton Total_Travel: 3.5mm (.138") Sealing: IP65 Rated (Dust-tight and protected against water jets) Operating_Temp: -25°C to +50°C (-13°F to +122°F) ``` ### 4. Application Use Cases Due to its **Gold Contacts** and **IP65** rating, this switch is ideal for: 1. **Industrial Control Panels:** Where dust or moisture splashes are common. 2. **Medical Equipment:** Requiring reliable, low-level logic switching. 3. **Communication Systems:** Used as a clear visual indicator for system states. 4. **Test & Measurement:** Where a latching (Alternate) action is needed to hold a circuit state.
