The **15TS-46-R** is a specific type of **Tactile Switch** (also known as a momentary push-button switch). These components are widely used in consumer electronics, industrial controls, and PCB designs to provide user input through a physical "click" sensation. --- ## 1. Technical Specifications The "15TS" series generally follows industry-standard footprints. Below are the typical technical characteristics for this specific part: | Parameter | Specification (Typical) | | :--- | :--- | | **Switch Type** | Tactile (Momentary) | | **Mounting Type** | Through-Hole (THT) or SMD (depends on suffix) | | **Circuit** | SPST-NO (Single Pole Single Throw - Normally Open) | | **Actuation Force** | 160gf to 250gf (grams-force) | | **Voltage Rating** | 12V DC | | **Current Rating** | 50mA | | **Contact Resistance** | < 100 mΩ | | **Insulation Resistance** | > 100 MΩ | | **Life Cycle** | 100,000 to 500,000 cycles | --- ## 2. Part Number Breakdown While manufacturer codes vary slightly, the nomenclature generally breaks down as follows: * **15TS**: The series identifier (often indicating a specific size/form factor, e.g., 6x6mm or 12x12mm). * **46**: Often refers to the **height** of the plunger (actuator) from the base (e.g., 4.6mm). * **R**: Usually denotes **RoHS Compliance** or **Tape & Reel** packaging. --- ## 3. Physical Construction A tactile switch like the 15TS-46-R consists of four main electronic/mechanical sub-parts: 1. **Cover/Bracket**: Usually metal, protects the internal mechanism and provides structural integrity. 2. **Actuator (Button)**: The plastic stem that the user presses. Its height (4.6mm in this case) determines how far it protrudes from the casing. 3. **Contact Dome**: A snap-action metal disc. When pressed, it collapses to bridge the circuit; when released, it springs back to the open position. 4. **Base/Terminals**: The plastic housing containing the silver-plated leads that are soldered to the PCB. --- ## 4. Typical Applications These switches are found in devices where a simple "On/Off" signal is required: * **Computer Peripherals**: Mouse buttons or reset switches. * **Home Appliances**: Microwave control panels or washing machine buttons. * **Consumer Electronics**: Remote controls, cameras, and handheld gaming devices. * **Microcontrollers**: Frequently used in Arduino or Raspberry Pi projects as a basic input sensor. --- ## 5. Circuit Diagram The switch acts as a simple bridge between two points: ```text (Press) | [ Actuator ] | /-------O (Terminal 1) | / | / (Contact Dome) | / \-------O (Terminal 2) ```
