The **MA13TBG-R** is an ultra-miniature, high-reliability toggle switch manufactured by **NKK Switches**. It is part of the **M series**, which is widely regarded for its durability and precise actuation in industrial and telecommunications equipment. Below is the technical breakdown of the electronic and mechanical specifications for this component. --- ### 1. General Specifications | Feature | Description | | :--- | :--- | | **Manufacturer** | NKK Switches | | **Series** | M Series (Miniature Toggles) | | **Switch Configuration** | SPDT (Single Pole Double Throw) | | **Switching Function** | ON-OFF-ON | | **Actuator Type** | Standard Bat Lever | | **Mounting Type** | PC Mount (Through-Hole) / Right Angle | --- ### 2. Electrical Characteristics The MA13TBG-R is designed for low-power (logic level) applications, featuring gold-plated contacts to ensure high reliability in signal switching. * **Contact Rating:** 0.4VA maximum @ 28V AC/DC maximum. * **Contact Resistance:** 20 milliohms maximum. * **Insulation Resistance:** 1,000 Megohms minimum @ 500V DC. * **Dielectric Strength:** 1,000V AC minimum between contacts for at least one minute. * **Mechanical Life:** 100,000 operations minimum. * **Electrical Life:** 50,000 operations minimum. --- ### 3. Physical & Material Composition The build quality of the M-series focuses on preventing environmental contamination and ensuring smooth mechanical movement. | Component | Material | | :--- | :--- | | **Contacts/Terminals** | Copper with Gold plating over Nickel | | **Housing** | Diallyl Phthalate (DAP) resin (UL94V-0) | | **Actuator** | Brass with Chrome plating | | **Bushing** | Brass with Nickel plating | | **Support Bracket** | Tin-plated Steel or Phosphor Bronze | --- ### 4. Key Features & Applications * **Anti-Rotation Design:** The actuator is designed with an internal "anti-rotation" feature to protect the internal contacts if the lever is twisted. * **Epoxy Sealed Terminals:** The base is sealed with epoxy to prevent flux, solvents, and other contaminants from entering the switch during soldering. * **Small Footprint:** Its right-angle PC mount configuration allows it to be used in tight spaces on PCBs where vertical height is limited. **Common Applications:** * Handheld medical devices. * Control panels for industrial automation. * Audio/Visual signal routing. * Telecommunication networking hardware. --- ### 5. Terminal Layout (ON-OFF-ON) As an SPDT (Single Pole Double Throw) switch with three positions: 1. **Position 1 (Left/Up):** Connects Pin 2 (Common) to Pin 3. 2. **Position 2 (Center):** All circuits open (OFF). 3. **Position 3 (Right/Down):** Connects Pin 2 (Common) to Pin 1.
