The **TS12S-R** is a high-precision, sub-miniature tactile switch commonly used in consumer electronics and industrial control panels. It is known for its "Soft Actuation" feel and surface-mount (SMD) design. --- ### 1. Technical Specifications The following table summarizes the primary electrical and mechanical characteristics of the TS12S-R: | Parameter | Specification | | :--- | :--- | | **Contact Type** | SPST (Single Pole Single Throw) | | **Circuitry** | Normally Open (N.O.) | | **Current Rating** | 50mA | | **Voltage Rating** | 12V DC | | **Operating Force** | 160gf ± 50gf (Standard) | | **Travel Distance** | 0.25mm ± 0.1mm | | **Contact Resistance** | 100mΩ Max | | **Insulation Resistance** | 100MΩ Min (at 100V DC) | | **Operating Life** | ~100,000 cycles | --- ### 2. Physical Construction The TS12S-R is comprised of several critical electronic and mechanical layers: * **Actuator (Stem):** The physical button pressed by the user. In the "R" variant, this is usually a low-profile round stem. * **Contact Dome:** A precision-engineered stainless steel or copper alloy disk. When pressed, it collapses to complete the circuit and provides the tactile "click." * **Terminals:** Silver-plated brass leads designed for **Surface Mount Technology (SMT/SMD)**. * **Base/Housing:** High-temperature thermoplastic (LCP or Nylon) capable of withstanding lead-free reflow soldering temperatures. --- ### 3. Key Features * **Compact Footprint:** Measuring approximately 12mm x 12mm (or smaller depending on specific series variations), it allows for high-density PCB layouts. * **Tactile Feedback:** Provides a distinct physical sensation to the user that the switch has been triggered. * **Reflow Solderable:** Designed to withstand the heat of automated pick-and-place assembly lines. --- ### 4. Typical Applications The TS12S-R is frequently found in: 1. **Consumer Electronics:** Remote controls, microwave panels, and digital cameras. 2. **Computing:** Reset buttons on motherboards or peripheral input devices. 3. **Industrial:** Interface panels for PLC (Programmable Logic Controllers).
