Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Circuit** | SPDT (Single Pole Double Throw) | | **Switch Function** | ON-OFF-ON | | **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 | --- ### 2. Breakdown of Parts and Components The MA11TBG-R is composed of several high-precision mechanical and electrical parts: #### A. The Actuator (Toggle) * **Material:** Usually brass with chrome plating. * **Function:** The physical lever that the user moves to change the state of the circuit. In this specific model, it is a standard length bat-style toggle. #### B. The Bushing * **Mounting:** It features a threaded bushing for panel mounting. * **Hardware:** Typically comes with two hex nuts, one locking ring, and one internal tooth lock washer to secure it to a chassis. #### C. Internal Contact System * **Movable Contactor:** A "rocker" mechanism inside the switch that snaps between positions to ensure a crisp tactile feel and reduce electrical arcing. * **Contact Material:** Silver alloy (standard) or gold-plated contacts (optional) to ensure high conductivity and prevent oxidation. #### D. The Base (Housing) * **Material:** Diallyl Phthalate (DAP) resin. * **Properties:** This is a high-strength, heat-resistant plastic that provides excellent electrical insulation between the terminals. #### E. Terminals * **Type:** Straight PC (Printed Circuit) terminals or Solder Lug, depending on the specific sub-variant. * **Sealing:** The base is often epoxy-sealed to prevent solder flux and contaminants from entering the switch mechanism during assembly. --- ### 3. Application Use Cases Due to its small footprint and high reliability, this component is commonly found in: * **Medical Equipment:** Control panels for diagnostic tools. * **Audio/Visual:** Professional mixing boards and signal routing. * **Industrial Controls:** Manual overrides for automated systems. * **Telecommunications:** Network switching and test equipment. ---
