The **TS-7G-R** is a specialized electronic component typically associated with high-precision switching or relay control modules, often found in industrial automation or automotive applications. Below is a breakdown of the electronic characteristics and internal parts common to this series. ### 1. Technical Specifications The TS-7G-R is generally categorized as a **Surface Mount Device (SMD)** tact switch or a specific relay variant depending on the manufacturer (often associated with brands like Diptronics or similar electronic component providers). | Parameter | Typical Value | | :--- | :--- | | **Contact Arrangement** | SPST (Single Pole Single Throw) | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Actuation Force** | 160gf to 260gf (Grams-force) | | **Voltage Rating** | 12V DC - 24V DC | | **Current Rating** | 50mA | | **Operating Temperature** | -25°C to +70°C | --- ### 2. Internal Electronic Components The device is comprised of several key physical parts that ensure electrical continuity: * **Actuator (Stem):** The top part that the user presses. It is usually made of heat-resistant plastic (LCP or Nylon) to withstand reflow soldering temperatures. * **Contact Dome:** A circular metal disc (often stainless steel with silver plating). This acts as the "bridge" that snaps down to complete the circuit when pressed. * **Base (Housing):** An insulating plastic base that holds the terminals in place. * **Terminals:** Copper alloy pins coated with silver or gold. These are the points soldered onto the PCB. * **Cover:** A metal plate (often stainless steel) that secures the internal parts and provides EMI shielding or grounding. --- ### 3. Key Features * **Tactile Feedback:** Designed to provide a "click" sensation to the user, confirming that the electrical connection has been made. * **Low Contact Resistance:** Usually under $100m\Omega$, ensuring minimal signal loss in low-voltage logic circuits. * **Reflow Solder Compatible:** The materials are designed to survive the high temperatures ($260^\circ C$) of automated industrial soldering ovens. --- ### 4.
