The **10SP-2A0-R** is a specific part number typically associated with **Tactile Switches** or **Pushbutton Switches**, often manufactured by companies like **Dailywell** or similar industrial component suppliers. These switches are designed for PCB (Printed Circuit Board) mounting and are commonly used in consumer electronics, telecommunications, and industrial control panels. --- ### 1. Technical Specifications Below are the typical specifications for this series of switches: | Feature | Specification | | :--- | :--- | | **Switch Type** | Pushbutton / Tactile Switch | | **Contact Rating** | 1A @ 250VAC; 3A @ 120VAC or 28VDC | | **Circuit** | SPDT (Single Pole Double Throw) | | **Function** | On-Mom (Momentary - springs back when released) | | **Mounting Type** | Through-Hole (PCB Mount) | | **Operating Force** | 250 ± 100 gf | | **Contact Resistance** | 20 mΩ max. initial | | **Dielectric Strength** | 1,000 Vrms at sea level | --- ### 2. Key Component Features * **Sub-Miniature Design:** The "10SP" series is known for a small footprint, making it ideal for high-density circuit boards where space is limited. * **Momentary Action:** The "Mom" function means the switch only stays in the "On" position while being pressed. It returns to its default state immediately upon release. * **Gold or Silver Plating:** These parts often feature silver-plated contacts for high conductivity or gold-plating for applications requiring low-level switching and corrosion resistance. * **Epoxy Seal:** The "-R" suffix often indicates compliance with environmental standards (like RoHS) or specific sealing (Epoxy base) to prevent contamination during soldering. --- ### 3. Applications The 10SP-2A0-R is versatile and can be found in: 1. **Audio Equipment:** Used as reset buttons or function selectors. 2. **Instrumentation:** Control panels for medical or laboratory devices. 3. **Networking:** Reset or power buttons on routers and modems. 4. **Peripheral Devices:** Buttons on computer hardware or industrial interfaces. --- ### 4. Terminal Configuration As an **SPDT** switch, it generally features three pins: 1. **Common (C):** The input pin. 2. **Normally Open (NO):** Connected to Common only when the button is pressed. 3. **Normally Closed (NC):** Connected to Common by default; disconnected when pressed.
