The part number **10AP-020-R** typically refers to a specific series of high-precision, sub-miniature **pushbutton switches**, often associated with manufacturers like *NKK Switches* or similar industrial component suppliers. Below is a technical breakdown of the component characteristics. --- ### 1. Technical Specifications This component is designed for logic-level applications where space on a Printed Circuit Board (PCB) is limited. | Feature | Specification | | :--- | :--- | | **Component Type** | Pushbutton Switch | | **Actuation** | Momentary (Non-locking) | | **Contact Rating** | 0.4VA Max @ 28V AC/DC Max | | **Mounting Type** | Through-hole (PCB Mount) | | **Terminal Type** | Right Angle (denoted by the "R" or specific suffix) | | **Circuitry** | SPST (Single Pole Single Throw) | | **Operating Force** | ~1.50 Newtons | --- ### 2. Key Design Features * **Sub-miniature Size:** These parts are engineered for high-density mounting. * **Sealed Construction:** Most variations feature an internal o-ring and ultrasonic welding to prevent contamination during the soldering and cleaning process. * **Gold Contacts:** Because the power rating is low (0.4VA), the contacts are usually gold-plated to ensure high reliability and prevent oxidation. * **Right Angle Orientation:** The "/R" or suffix often indicates a right-angle terminal configuration, allowing the switch to be mounted on the edge of a board for horizontal access. --- ### 3. Pinout and Mechanical Layout Most switches in this category follow a standard 2.54mm (0.1") pitch for PCB compatibility. ```text [ Actuator ] | | ______|___|______ | | | Switch Body | |_________________| | | | (1) (2) (3) <-- Right Angle Pins ``` --- ### 4. Typical Applications * **Handheld Devices:** Due to the small footprint. * **Reset Buttons:** Common in embedded systems. * **Interface Selection:** Used on industrial control panels for menu navigation. * **Medical Equipment:** Where high reliability in small form factors is required.
