The **CFS-0601TB** is a surface-mount (SMD) DIP switch typically manufactured by companies like **Copal Electronics** (now Nidec Components). It is a slide-type switch designed for compact electronic circuits where manual configuration is required. --- ### 1. Technical Specifications Below are the primary electrical and mechanical characteristics of the CFS-0601TB: | Feature | Specification | | :--- | :--- | | **Switch Type** | DIP (Dual In-line Package) | | **Number of Positions** | 6 Positions | | **Actuator Type** | Slide (Flush / Recessed) | | **Mounting Type** | Surface Mount (SMD / SMT) | | **Pitch** | 1.27 mm (Half-pitch) | | **Contact Rating (Switching)** | 100mA @ 5V DC | | **Contact Rating (Non-switching)** | 100mA @ 50V DC | | **Operating Temperature** | -40°C to +85°C | --- ### 2. Key Component Features * **Half-Pitch Design:** Unlike standard DIP switches with a 2.54mm pitch, the CFS-0601TB uses a **1.27mm pitch**. This makes it significantly smaller, saving valuable PCB real estate. * **Gold-Plated Contacts:** To ensure high reliability and prevent oxidation over time, the internal contacts are typically gold-plated. * **Bifurcated Contact Mechanism:** This design provides twin contact points for every position, ensuring a stable connection even in environments with high vibration. * **Washable/Sealed:** The "TB" suffix often indicates the packaging or sealing method. These switches are usually designed to withstand lead-free soldering processes and can often be washed if they have a top-seal tape. --- ### 3. Pin Configuration and Circuitry The device consists of 6 independent SPST (Single Pole Single Throw) switches housed in one block. ```text [ Top View ] ON 1 2 3 4 5 6 | | | | | | <-- Actuators ----------- | | | | | | <-- Terminals ``` ### 4. Common Applications * **Industrial Controls:** Setting Modbus or CAN bus node IDs. * **Consumer Electronics:** Mode selection or feature toggling on compact devices. * **Telecommunications:** Configuring line settings on networking hardware. * **Medical Equipment:** Internal calibration settings that do not require user access. ---
