The **HSP-13-R** is an electronic component primarily classified as a **horizontal-type push-button switch**. These components are widely used in consumer electronics, automotive interiors, and industrial control panels due to their tactile feedback and reliable switching mechanism. --- ### 1. Technical Specifications The HSP-13-R is designed for low-power signal switching. Below are the typical technical parameters: | Feature | Specification | |:---|:---| | **Switch Type** | Push Button (Horizontal) | | **Circuit Type** | SPST (Single Pole Single Throw) or SPDT | | **Mounting Type** | Through-hole / SMT (Surface Mount) | | **Contact Resistance** | ≤ 100mΩ | | **Insulation Resistance** | ≥ 100MΩ (at 250V DC) | | **Operating Force** | 160gf to 250gf (typical) | | **Life Cycle** | 10,000 to 50,000 cycles | --- ### 2. Key Internal Components To understand the "electronic parts" of the HSP-13-R, we must look at its internal construction: * **Actuator (Stem):** The physical part the user presses. Usually made of high-temperature plastic (LCP or Nylon). * **Contact Dome/Spring:** A metallic leaf (often phosphor bronze or stainless steel) that snaps down to complete the circuit when pressed. This provides the "click" sound. * **Terminals:** The conductive metal legs that connect the switch to the PCB. These are usually silver-plated to ensure high conductivity and prevent oxidation. * **Base/Housing:** The frame that holds all internal parts together, typically made of heat-resistant thermoplastic to withstand soldering temperatures. --- ### 3. Footprint and Pinout The HSP-13-R generally follows a horizontal orientation, meaning the button is pressed parallel to the PCB surface rather than vertically. ```text PCB Layout View (Example): [ Terminal 1 ] ---- ( Internal Switch ) ---- [ Terminal 2 ] | | [ Pin A ] [ Pin B ] ``` --- ### 4. Common Applications * **Audio/Visual Equipment:** Mode selection buttons on cameras or MP3 players. * **Household Appliances:** Power buttons on small handheld devices. * **Communication Devices:** Reset buttons or function toggles on routers and modems.
