The **10TS-120-R** is a specific model within the series of high-quality **Tactile Switches**. These components are widely used in electronic interfaces to provide physical feedback (a "click") to the user when a circuit is closed. --- ### 1. Technical Specifications The following table highlights the core electronic and mechanical characteristics of the 10TS-120-R: | Parameter | Specification | | :--- | :--- | | **Switch Type** | Tactile (Momentary Pushbutton) | | **Mounting Type** | Surface Mount Device (SMD/SMT) | | **Actuation Force** | 120gf (Grams-force) ± 30gf | | **Contact Rating** | 50mA @ 12V DC | | **Contact Resistance** | 100mΩ Max | | **Insulation Resistance** | 100MΩ Min @ 100V DC | | **Dielectric Strength** | 250V AC for 1 minute | | **Operating Life** | 100,000 to 500,000 cycles (Typical) | --- ### 2. Physical Dimensions & Design * **Form Factor:** Usually features a compact footprint (often 3x6mm or 6x6mm depending on the specific manufacturer's sub-series). * **Actuator Height:** The "120" in the series often relates to the actuation force, but specific heights are defined in the datasheet (typically ranging from 2.5mm to 5.0mm). * **Termination:** Gull-wing leads designed for automated SMT pick-and-place assembly. * **Material:** High-temperature thermoplastic base to withstand lead-free reflow soldering processes. --- ### 3. Circuit Configuration The 10TS-120-R is a **SPST-NO** (Single Pole Single Throw - Normally Open) switch. ```text (Terminal 1) ----/ ---- (Terminal 2) (Switch) ``` * **Resting State:** The circuit is open (No current flows). * **Pressed State:** The internal metal dome collapses, connecting the terminals (Current flows). * **Release State:** The dome springs back, breaking the connection. --- ### 4. Key Applications Because of its small size and reliable tactile feedback, this part is commonly found in: 1. **Consumer Electronics:** Mobile phones, remote controls, and wearables. 2. **Computing:** Reset buttons on motherboards or peripheral buttons. 3. **Industrial:** Control panels and membrane keypad interfaces. 4. **Automotive:** Dashboard controls and key fobs.
