The **M2TS-0B-R** is a specific model of a **Miniature Toggle Switch**, typically manufactured by companies like **NKK Switches**. These components are widely used in industrial control panels, medical equipment, and telecommunications for their reliability and compact size. --- ### 1. Technical Specifications Below is a breakdown of the key electronic and physical characteristics: | Feature | Specification | | :--- | :--- | | **Switch Function** | ON - ON (Single Pole Double Throw - SPDT) | | **Current Rating** | 6A @ 125V AC / 3A @ 250V AC | | **Contact Resistance** | 10 milliohms maximum | | **Insulation Resistance** | 1,000 Megohms minimum @ 500V DC | | **Dielectric Strength** | 1,000V AC minimum for 1 minute | | **Mechanical Life** | 100,000 operations minimum | | **Terminal Type** | Solder Lug | --- ### 2. Component Composition The device is composed of several critical materials designed for durability and conductivity: * **Actuator:** Usually a chrome-plated brass lever, providing a sturdy tactile feel. * **Bushing:** Threaded brass with nickel plating, used for panel mounting. * **Case:** Diallyl Phthalate (DAP) resin or high-temperature UL94V-0 plastic, which acts as an excellent insulator. * **Contacts:** Silver alloy (standard) or gold plating (for low-level logic signals). * **Terminals:** Epoxy sealed to prevent flux or contaminants from entering the switch body during soldering. --- ### 3. Circuit Application (SPDT) The **M2TS-0B-R** operates as a **Single Pole Double Throw** switch. This means it has one input (Common) and two possible outputs. ```text [Terminal 2: Common] / / <-- Lever Position / [Terminal 1] [Terminal 3] (Output A) (Output B) ``` 1. **Position 1:** Connects Terminal 2 to Terminal 1. 2. **Position 2:** Connects Terminal 2 to Terminal 3. --- ### 4. Part Number Breakdown (NKK M2 Series) * **M2:** Represents the series (Miniature Toggle). * **T:** Denotes the toggle actuator type. * **S:** Refers to the standard bushing/bracket size. * **0B:** Often indicates the specific circuit configuration (ON-ON) and terminal style. * **-R:** Generally indicates compliance with **RoHS** (Restriction of Hazardous Substances) standards.
