The **APTE-6112-R** is a specific electronic component primarily used in consumer electronics, industrial interfaces, and communication devices. It is a **Tactile Switch** (also known as a momentary push-button switch). --- ## 1. Component Overview The APTE-6112-R is a surface-mount device (SMD) designed to provide physical feedback to a user when a button is pressed. It is engineered for durability and high-density PCB mounting. ### Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Type** | Tactile Switch (Momentary) | | **Mounting Type** | Surface Mount (SMD / SMT) | | **Circuit** | SPST-NO (Single Pole Single Throw - Normally Open) | | **Actuator Style** | Standard Round Plunger | | **Contact Rating** | Typically 50mA @ 12VDC | | **Operating Force** | 160gf (grams-force) ± 50gf | | **Travel distance** | 0.25mm | | **Operating Life** | ~100,000 Cycles | --- ## 2. Internal Construction The "Electronic Parts" of this switch consist of four primary elements: 1. **The Contact Dome:** A stainless steel or copper alloy disc. When pressed, it collapses to bridge the gap between two terminals, completing the circuit. 2. **Terminals:** Usually silver-plated or gold-plated brass for high conductivity and oxidation resistance during soldering. 3. **Base/Housing:** Made of high-temperature thermoplastic (like LCP or Nylon) to withstand reflow soldering temperatures. 4. **Actuator (Stem):** The physical part the user pushes, which transfers the force to the internal dome. --- ## 3. Electrical Characteristics * **Contact Resistance:** Usually less than $100m\Omega$. * **Insulation Resistance:** Minimum $100M\Omega$ at 100VDC. * **Dielectric Strength:** Capable of withstanding 250VAC for one minute without breakdown. * **Bounce Time:** Maximum 10ms (the time it takes for the signal to stabilize after the physical press). --- ## 4. Application Examples The APTE-6112-R is commonly integrated into the following systems: * **Computer Peripherals:** Reset buttons or mode selectors. * **Handheld Devices:** Power buttons or volume controls. * **Home Appliances:** Control panels for microwave ovens or washing machines. * **Medical Equipment:** Interface buttons on monitoring devices. ---
