The **RC-2MTS-50** generally refers to a specific type of **Miniature Toggle Switch** commonly used in electronics prototyping, industrial control panels, and hobbyist projects. This part is characterized by its "Micro" size and "Double Pole Double Throw" (DPDT) configuration. ### Technical Specifications | Feature | Specification | | :--- | :--- | | **Model Number** | RC-2MTS-50 (Series) | | **Type** | Miniature Toggle Switch | | **Circuit Configuration** | DPDT (Double Pole Double Throw) | | **Switching Positions** | ON-ON (2-Position) | | **Contact Rating** | Usually 5A @ 125VAC or 2A @ 250VAC | | **Terminal Type** | Solder Lug | | **Mounting Diameter** | Approx. 6mm (1/4") | --- ### Core Electronic Components #### 1. Contact Mechanism (DPDT) The "2" in the part number often signifies the number of poles. A **DPDT** switch functions like two separate SPDT switches controlled by a single lever. * **Terminals:** It typically has 6 pins on the bottom. * **Function:** It can control two independent circuits simultaneously or reverse the polarity of a DC motor. #### 2. The Actuator (Toggle) The "MTS" stands for **Miniature Toggle Switch**. The actuator is the metal lever that the user moves. * **Bushing:** The threaded part that goes through the panel. * **Locking Mechanism:** Internal springs ensure a "snap-action" movement, providing tactile feedback and ensuring the contact is firm to prevent electrical arcing. #### 3. Dielectric Housing The body is usually made of **Diallyl Phthalate (DAP)** or high-temperature plastic. This material provides high insulation resistance, ensuring that current does not leak between the six terminals. #### 4. Contacts and Terminals * **Material:** Usually silver-plated or gold-plated copper alloy. * **Resistance:** Designed for low contact resistance (typically <10mΩ) to minimize heat buildup during operation. --- ### Typical Use Cases * **Polarity Reversal:** Wiring the DPDT switch in an "X" pattern to change the direction of a DC motor. * **Audio Equipment:** Switching between two different signal inputs or bypassing an effect circuit. * **Power Control:** Turning on two separate power rails (e.g., +5V and +12V) with a single flick.
