Based on the part number **10TS-046-R**, this component typically refers to a **Tactile Switch** (also known as a momentary push-button switch) commonly used in PCB designs. --- ### 1. Component Overview The 10TS-046-R is a miniature electronic switch that completes an electrical circuit only when the button is physically pressed. Once released, the switch returns to its open (off) position. ### 2. Technical Specifications While specific manufacturers may have slight variations, the general specifications for this series are: | Parameter | Specification (Typical) | | :--- | :--- | | **Switch Type** | Tactile / Momentary | | **Actuator Height** | 4.3mm - 5.0mm (standard) | | **Mounting Type** | Through-Hole (THT) | | **Circuit** | SPST (Single Pole Single Throw) | | **Contact Rating** | 50mA @ 12V DC | | **Operating Force** | 160gf to 250gf | | **Life Expectancy** | ~100,000 cycles | | **Contact Resistance** | < 100 mΩ | --- ### 3. Physical Construction The "R" in the suffix often denotes **RoHS Compliance** or specific packaging (like Tape & Reel), though in tactile switches, it usually confirms environmental compliance. * **Actuator:** The top button usually made of plastic. * **Cover:** Metal plate holding the components together. * **Contact Dome:** A stainless steel or copper alloy disc that provides the "click" feel and completes the circuit. * **Base:** Heat-resistant molded plastic. * **Terminals:** Usually four pins (internally connected in pairs for stability). --- ### 4. Common Applications Due to its small footprint and reliability, the 10TS-046-R is used in: 1. **Consumer Electronics:** Remote controls, microwave panels, and calculators. 2. **Computing:** Reset buttons on motherboards or peripheral devices. 3. **Industrial:** Control panels and interface modules. 4. **DIY/Prototyping:** Breadboard-friendly testing buttons. --- ### 5. Circuit Diagram (Internal Connection) The switch typically has four pins. Pins 1 and 2 are internally connected, and pins 3 and 4 are internally connected. Pressing the button bridges the gap between the 1-2 pair and the 3-4 pair. ```text Pin 1 ----|---- Pin 3 | (Switch) Pin 2 ----|---- Pin 4 ```
