The **M2TS-5A-R** is a specific model of a **Miniature Toggle Switch** typically manufactured by companies like Mountain Switch or similar electronic component suppliers. It is designed for PCB (Printed Circuit Board) mounting and is used to control the flow of current in small electronic devices. --- ### 1. Technical Specifications Below are the primary electrical and mechanical specifications for this component: | Feature | Specification | | :--- | :--- | | **Switch Type** | Toggle Switch | | **Circuit** | SPDT (Single Pole Double Throw) | | **Switch Function** | ON-OFF-ON (Three positions) | | **Current Rating** | 5A @ 125VAC or 28VDC; 2A @ 250VAC | | **Terminal Type** | PC Pins (Right Angle / Vertical options) | | **Contact Resistance** | 10 mΩ max | | **Insulation Resistance** | 1,000 MΩ min | | **Dielectric Strength** | 1,500 V RMS @ sea level | | **Operating Temperature** | -30°C to +85°C | --- ### 2. Key Component Parts The device consists of several critical internal and external parts that define its functionality: #### A. The Actuator (Toggle Lever) The "bat" or handle, usually made of chrome-plated brass. In the **5A-R** series, this is the part the user flips to change the state of the circuit. #### B. Contact Mechanism * **Movable Contact:** A silver-plated copper alloy "rocker" that moves between the stationary terminals. * **Stationary Terminals:** These are the pins that solder into your PCB. They are usually silver-plated to ensure high conductivity and low oxidation. #### C. Housing and Base * **Case:** Usually made of Diallyl Phthalate (DAP), a high-strength plastic with excellent electrical insulation properties and heat resistance (important during soldering). * **Bushing:** The threaded part (if applicable) that allows the switch to be mounted through a panel. #### D. The "R" Suffix In many electronic naming conventions, the **-R** suffix denotes that the component is **RoHS Compliant**, meaning it is manufactured without hazardous substances like lead. --- ### 3. Circuit Configuration (SPDT) The M2TS-5A-R typically utilizes an **ON-OFF-ON** configuration: 1. **Position 1:** Pin 2 is connected to Pin 1. 2. **Center Position:** No pins are connected (Circuit is Open/Off). 3. **Position 3:** Pin 2 is connected to Pin 3. ---
