### Overview: YB215CWCKG01-24-EB The **YB215CWCKG01-24-EB** is a high-quality, illuminated pushbutton switch manufactured by **NKK Switches**. It belongs to the YB Series, which is known for its modular design, durability, and tactile feedback. --- ### Technical Specifications The part number can be broken down into specific electronic and mechanical characteristics: | Feature | Specification | | :--- | :--- | | **Switch Type** | Pushbutton (Momentary) | | **Circuit** | DPDT (Double Pole, Double Throw) | | **Contact Rating** | 0.4VA Max @ 28V AC/DC (Logic Level) | | **Contact Material** | Gold Plated (Ideal for low-power circuits) | | **Illumination Type** | LED (Integrated) | | **LED Voltage** | 24V DC | | **Cap Color/Style** | Yellow (E), Round, Flush Mount | | **Bezel Color** | Black (B) | | **Mounting Type** | Panel Mount, 16mm Cutout | --- ### Electronic Components Breakdown #### 1. DPDT Circuitry The **DPDT (Double Pole Double Throw)** configuration means the switch controls two separate circuits simultaneously. Each "pole" has a common terminal that can switch between a Normally Open (NO) and Normally Closed (NC) contact. #### 2. Logic Level Gold Contacts Unlike silver contacts designed for high-current power switching, the gold-plated contacts in this model are engineered for **Logic Level** applications. - **Benefit:** Gold prevents oxidation, ensuring high reliability when switching very low currents (micro-amps) and voltages. #### 3. Integrated LED Illumination The "24-EB" suffix indicates the lighting parameters: - **Voltage:** Pre-configured for **24V DC** operation. This usually includes an internal resistor to protect the LED at this specific voltage. - **Color:** Yellow illumination matching the yellow cap. #### 4. Termination This model typically features **Solder Lug** terminals. These terminals are designed for manual wiring or can be used with quick-connect connectors if appropriately sized. --- ### Physical & Environmental Data - **Sealing:** It is rated **IP65** (Dust-tight and protected against water jets), making it suitable for industrial control panels. - **Mechanical Life:** 1,000,000 cycles minimum. - **Electrical Life:** 100,000 cycles minimum at full load.
