Based on the part number **CFPB-1CC-1O2**, this component belongs to the **CFPB Series** of illuminated tactile switches manufactured by **Nidec Components (formerly Copal Electronics)**. These are high-quality, subminiature push-button switches designed for PC board mounting, commonly used in control panels and professional audio equipment. --- ### 1. Technical Specifications The following table breaks down the primary electrical and mechanical characteristics of the CFPB-1CC-1O2: | Parameter | Specification | | :--- | :--- | | **Switch Function** | SPDT (Single Pole Double Throw) | | **Switching Action** | Momentary (ON- (ON)) | | **Current Rating** | 100mA @ 30VDC | | **Contact Resistance** | 50 mΩ maximum | | **Dielectric Strength** | 250VAC for 1 minute | | **Operating Force** | 1.57 ± 0.49 N (approx. 160gf) | | **Stroke** | 1.3 mm | | **Operating Temperature** | -25°C to +70°C | --- ### 2. Part Number Breakdown Understanding the nomenclature helps identify the specific features of this model: | Segment | Code | Meaning | | :--- | :--- | :--- | | **Series** | `CFPB` | Subminiature Illuminated Pushbutton Switch | | **Terminal Style** | `1` | PC Board (Through-hole) terminals | | **Circuitry** | `CC` | SPDT (On - (On)) | | **Button Shape** | `1` | Square Button | | **LED Color** | `O` | Orange LED | | **Cap Color** | `2` | White Cap | --- ### 3. Key Electronic Features * **Illumination:** This specific model features an **Orange LED**. Because it is a built-in LED, you must ensure the circuit includes a proper current-limiting resistor to prevent burning out the diode. * **Contact Reliability:** The contacts are typically gold-plated, ensuring high reliability even in low-current (logic level) switching applications. * **Tactile Feedback:** Despite being a pushbutton, it provides a distinct "click" feel, informing the user that the connection has been made. * **Form Factor:** It is a "subminiature" switch, meaning it has a very small footprint (approx. 7mm to 10mm square), making it ideal for high-density circuit boards. --- ### 4.
