The **6TC-R** is a specific model of a **Miniature Slide Switch**, commonly manufactured by brands like **Dailywell** or **Taiway**. These switches are designed for PCB (Printed Circuit Board) mounting and are widely used in telecommunications, instrumentation, and medical equipment. --- ### 1. Key Electronic Specifications Below are the typical technical parameters for the 6TC-R series: | Parameter | Specification | | :--- | :--- | | **Contact Rating** | 5A @ 120VAC or 28VDC; 2A @ 250VAC | | **Electrical Life** | 30,000 make-and-break cycles at full load | | **Contact Resistance** | 10 mΩ max. initial @ 2-4VDC | | **Insulation Resistance** | 1,000 MΩ min. | | **Dielectric Strength** | 1,000 Vrms min. @ sea level | | **Operating Temperature** | -30°C to 85°C | --- ### 2. Physical Components & Materials The construction of the 6TC-R involves several specialized materials to ensure durability and conductivity: * **Case & Bushing:** Usually made of Glass Filled Nylon 6/6, Flame Retardant, Heat Stabilized (UL94V-0). * **Actuator:** Nylon (UL94V-0) with an internal O-ring seal to prevent contamination. * **Switch Support:** Retinned brass or stainless steel. * **Contacts / Terminals:** Silver-plated copper alloy (standard) or Gold-plated for low-power applications. --- ### 3. Part Number Breakdown (6TC-R Series) While specific suffixes may vary by manufacturer, the code generally breaks down as follows: 1. **6 (Series ID):** Identifies it as a sub-miniature slide switch series. 2. **T (Terminal):** Often denotes the terminal type (e.g., PC thru-hole, right angle, or surface mount). 3. **C (Contact Material):** Frequently signifies silver contacts (standard power rating). 4. **R (RoHS/Right Angle):** Usually indicates **RoHS compliance** or a **Right-Angle** mounting orientation. --- ### 4. Circuit Options The 6TC-R is typically available in several pole/throw configurations: * **SPDT:** Single Pole Double Throw (On-On or On-Off-On). * **DPDT:** Double Pole Double Throw. --- ### 5. Application Example (Simple Diagram) When wiring a 6TC-R as a power selector: ```text [Terminal 1] ----> Battery A (+) [Terminal 2] ----> Device Input (+) (Common) [Terminal 3] ----> Battery B (+) ```
