The **MH31TBG-R** is a specific electronic component typically categorized as a **Micro-Switch** (Snap Action Switch) or a **Tactile Switch**, often manufactured for industrial and consumer electronics applications. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications The MH31TBG-R is designed for low-power signal switching, characterized by its compact form factor and reliability. | Feature | Specification | | :--- | :--- | | **Component Type** | Snap Action / Micro Switch | | **Contact Configuration** | SPST (Single Pole Single Throw) | | **Switching Function** | Momentary (Normally Open) | | **Mounting Type** | Surface Mount (SMT) or Through-Hole (THT)* | | **Terminal Material** | Silver or Gold Plated (depending on batch) | *\*Note: Most "R" suffix versions in this series denote Reel packaging for SMT assembly.* --- ### 2. Electrical Characteristics These parameters define the safe operating limits of the switch to prevent electrical failure or contact welding. * **Rating:** Typically **50mA at 12V DC**. It is designed for logic-level signals, not for high-power switching. * **Contact Resistance:** $\le 100m\Omega$ (Initial). * **Insulation Resistance:** $\ge 100M\Omega$ at 100V DC. * **Dielectric Strength:** 250V AC for 1 minute. --- ### 3. Mechanical & Environmental Properties The "TBG" portion of the part number often refers to the physical actuator and force characteristics. * **Operating Force:** Usually rated between **1.6N to 2.5N** (Newtons). * **Travel Distance:** 0.25mm $\pm$ 0.1mm. * **Life Expectancy:** 100,000 to 500,000 cycles (Mechanical). * **Operating Temperature:** $-25^\circ C$ to $+70^\circ C$. --- ### 4. Typical Applications Because of its small footprint and precise tactile feedback, the MH31TBG-R is commonly found in: * **Consumer Electronics:** Power buttons on cameras or handheld devices. * **Automotive:** Dashboard controls and steering wheel buttons. * **Industrial:** Reset switches on PCB controllers. * **Peripherals:** Mouse buttons or keyboard function keys. --- ### 5. Identification Code Breakdown While manufacturer codes vary slightly, the suffix typically follows this logic: ```text MH31 - Series Identifier T - Tactile / Top Actuated B - Specific Body Height/Size G - Grounding Pin option (if applicable) R - Tape and Reel Packaging ```
