The **YB215CWCPG01-5F-EB** is a specific part number for a high-quality, illuminated pushbutton switch manufactured by **NKK Switches**. This component belongs to the YB Series, which is known for its compact design and modular flexibility. Below is a breakdown of its technical specifications and electronic characteristics. --- ### 1. Part Number Decoder Understanding the alphanumeric code reveals the specific features of this switch: | Segment | Meaning | Specification | | :--- | :--- | :--- | | **YB2** | Series | YB Series (Panel Seal, Compact) | | **15** | Circuit | SPDT (Single Pole Double Throw) | | **CW** | Actuator Style | Square, Flush Mount | | **CPG** | Contact Material | Gold Contacts (Low Logic Level) | | **01** | Terminals | Solder Lug | | **5F** | LED Color | Green LED (Standard Brightness) | | **EB** | Cap Color/Type | Yellow Cap (Opaque/Translucent) | --- ### 2. Electrical Specifications This switch is designed primarily for low-power signal switching rather than high-current power applications. * **Contact Rating:** 0.4VA maximum @ 28V AC/DC maximum. (Gold contacts are used for reliability in dry circuits). * **Contact Resistance:** 50 milliohms maximum. * **Insulation Resistance:** 200 megohms minimum @ 500V DC. * **Dielectric Strength:** 1,000V AC minimum between contacts for at least one minute. * **Mechanical Life:** 1,000,000 operations minimum. * **Electrical Life:** 100,000 operations minimum. --- ### 3. Physical & Environmental Features The YB series is often selected for industrial or commercial panels requiring durability. * **Illumination:** Integrated Green LED (requires a current-limiting resistor depending on the input voltage). * **Sealing:** Rated **IP65** (Dust-tight and protected against water jets), making it suitable for harsh environments. * **Switching Action:** Momentary (the switch returns to its original position after being released). * **Panel Cutout:** 16mm diameter round hole. * **Operating Temperature:** -25°C to +50°C (-13°F to +122°F) for illuminated models. --- ### 4. Connection Diagram (Internal) The SPDT configuration typically follows this pinout logic: ```text [ LED + ] [ LED - ] | | ------------------------- | (1) Common (C) | | (2) Normally Open (NO)| | (3) Normally Closed(NC)| ------------------------- ``` --- ### Summary Recommendation This part is ideal for **logic-level applications** (interfacing with Microcontrollers, PLCs, or TTL circuits) where moisture resistance and visual feedback (Green LED) are required. Because it uses **gold contacts**, it should **not** be used for high-power switching (e.g., directly driving a 120V motor), as the gold plating will burn off.
