The **F2TS-12-R** is a specific model of a **Miniature Toggle Switch**, typically manufactured by companies like **Fujisoku** (now part of Nidec Components). It is designed for PCB mounting and is characterized by its compact size and high reliability. --- ### 1. Technical Specifications The following table outlines the primary electrical and mechanical characteristics of the F2TS-12-R: | Feature | Specification | | :--- | :--- | | **Switch Type** | Toggle Switch | | **Circuit Configuration** | SPDT (Single Pole Double Throw) | | **Switch Function** | ON - ON (2 positions) | | **Contact Rating** | 0.4VA Max @ 28V AC/DC (Logic Level) | | **Contact Resistance** | 100 mΩ max | | **Insulation Resistance** | 500 MΩ min | | **Dielectric Strength** | 500V AC for 1 minute | | **Mechanical Life** | 50,000 cycles | | **Terminal Type** | PC Terminal (Right Angle) | --- ### 2. Key Features and Construction * **Gold-Plated Contacts:** The "R" in the suffix often denotes gold plating. This is critical for low-power (logic level) circuits to prevent oxidation and ensure a stable connection over time. * **Washable Construction:** These switches are usually designed to be process-sealed, allowing them to withstand automated wave soldering and cleaning processes without internal contamination. * **Right-Angle Mounting:** The leads are bent at a 90-degree angle, allowing the toggle to be actuated from the side of a printed circuit board (PCB), making it ideal for edge-mounted controls. * **Compact Footprint:** Part of the "F" series, these are minimized in size to fit into handheld devices or dense control panels. --- ### 3. Pinout and Circuit Logic As an **SPDT** switch, it has three terminals. The logic operates as follows: | Toggle Position | Connected Pins | | :--- | :--- | | **Position 1 (Left/Up)** | Center Pin (2) connects to Pin 3 | | **Position 2 (Right/Down)** | Center Pin (2) connects to Pin 1 | --- ### 4. Common Applications * **Portable Instruments:** Due to the small size and low power rating. * **Telecommunications:** Used for mode selection or reset functions. * **Medical Equipment:** Reliable switching for handheld diagnostic tools. * **Industrial Controls:** Board-level configuration switches.
