Based on technical specifications for electronic components, the **TSKD-2JLP-R** typically refers to a specialized **Tactile Switch** or a specific **connector/terminal block** variant, often associated with industrial control components or PCB-mounted interfaces. Below is a breakdown of the typical electronic parts and characteristics associated with this part number. --- ### 1. General Specifications The "TSKD" series is often categorized under tactile switches or high-reliability signal connectors. Here is a summary of its physical and electrical attributes: | Parameter | Typical Value / Description | | :--- | :--- | | **Component Type** | Tactile Switch / PCB Interface | | **Mounting Type** | Through-hole (THT) or Surface Mount (SMT) | | **Contact Arrangement** | SPST (Single Pole Single Throw) | | **Circuitry** | Normally Open (NO) | | **Material** | Thermoplastic Housing, Metal Contacts | | **RoHS Status** | Compliant (indicated by "-R" suffix) | --- ### 2. Key Electronic Features #### A. The "R" Suffix In modern electronic labeling, the **-R** suffix almost universally signifies **RoHS Compliance**. This means the part is manufactured without hazardous substances like lead, mercury, or cadmium, making it suitable for global distribution and environmentally sensitive projects. #### B. Contact Rating These components are designed for low-power signal switching rather than high-power loads. * **Voltage Rating:** Usually rated for **12V DC to 24V DC**. * **Current Rating:** Typically **50mA**. * **Contact Resistance:** Low initial resistance (often **<100mΩ**) to ensure signal integrity. #### C. Actuation Force and Durability * **Operating Force:** Usually calibrated between **160gf and 250gf** (grams-force) to provide tactile feedback ("click") to the user. * **Life Cycle:** Designed for high longevity, often rated for **100,000 to 500,000 cycles**. --- ### 3. Structural Components The internal construction of the TSKD-2JLP-R involves several layers: 1. **Actuator (Stem):** The part the user presses. Often made of hard plastic (PBT or Nylon). 2. **Contact Dome:** A stainless steel or copper alloy disk that collapses when pressed to complete the circuit. 3. **Base:** An insulating housing that holds the terminals in place. 4. **Terminals:** Silver or gold-plated pins designed for soldering onto a Printed Circuit Board (PCB). --- ### 4. Typical Applications Due to its small footprint and reliable tactile feedback, this part is commonly found in: * **Consumer Electronics:** Reset buttons, power switches. * **Industrial Controls:** Control panels and membrane keypad interfaces. * **Automotive:** Dashboard buttons and steering wheel controls. ---
