The **WJT-N24-R** is a specific electronic component primarily identified as a **Micro Tactile Switch** (also known as a Push Button Switch). These components are widely used in consumer electronics, automotive controls, and industrial interfaces to provide a physical "click" feedback to the user. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications The WJT series generally follows standard surface-mount (SMD) or through-hole (DIP) configurations. The "N24" suffix often denotes the specific physical height or actuation force. | Feature | Specification (Typical) | | :--- | :--- | | **Type** | Momentary Tactile Switch | | **Circuitry** | SPST (Single Pole, Single Throw) | | **Current Rating** | 50mA | | **Voltage Rating** | 12V DC | | **Contact Resistance** | ≤ 100mΩ | | **Insulation Resistance** | ≥ 100MΩ (100V DC) | | **Dielectric Strength** | 250V AC for 1 minute | --- ### 2. Physical & Mechanical Properties The "R" in the part number often signifies **RoHS Compliance** or **Reel Packaging** (Tape & Reel) for automated pick-and-place assembly. * **Actuation Force:** Usually ranges between **160gf to 250gf** (grams-force). This determines how hard the user must press to trigger the switch. * **Travel Distance:** Typically **0.25mm**, providing a sharp, tactile "click" sensation. * **Operating Life:** Rated for approximately **50,000 to 100,000 cycles**, depending on the specific sub-variant. * **Mounting Type:** Likely **SMD (Surface Mount Device)**, designed for modern PCB layouts. --- ### 3. Pinout & Internal Structure Inside the WJT-N24-R, there is a small metal dome. When pressed, the dome collapses and connects two internal traces, closing the circuit. 1. **Terminals:** Usually 4 pins (2 pairs connected internally). 2. **Actuator:** The button (plunger) that the user presses. 3. **Cover:** A metal or plastic shield protecting the internal dome. 4. **Base:** The plastic housing that holds the terminals in place. --- ### 4. Common Applications Due to its small footprint and reliability, this part is found in: * **Consumer Electronics:** Remote controls, microwave panels, and digital cameras. * **Computing:** Mouse buttons or reset switches on motherboards. * **Portable Devices:** Handheld game consoles and wearable tech. ---
