The **M2TT-45-R/C** (often associated with the M2 series by manufacturers like Nidec Copal or similar precision component providers) typically refers to a **miniature toggle switch** designed for PC board mounting. Below is a detailed breakdown of its electronic and physical specifications. --- ## 1. Component Overview The "M2" series represents a line of sub-miniature switches designed for high reliability and space-saving on printed circuit boards (PCBs). ### Technical Specifications | Feature | Description | | :--- | :--- | | **Switch Type** | Toggle Switch | | **Circuit Configuration** | DPDT (Double Pole, Double Throw) | | **Switching Function** | ON-ON (Maintained) | | **Current Rating** | Typically 6A @ 125VAC or 3A @ 250VAC | | **Terminal Type** | Right Angle PC Terminals (R/C designation) | | **Actuator Style** | Standard Bat Lever | | **Contact Material** | Usually Silver (standard) or Gold (logic level) | --- ## 2. Key Features * **Space Efficiency:** The "R/C" suffix usually indicates a **Right Angle** orientation, meaning the toggle flips horizontally relative to the PCB. This is ideal for side-panel access. * **High Contact Reliability:** Features a "twin-contact" or reinforced mechanism to prevent contact failure over thousands of cycles. * **Heat Resistance:** The body is constructed from high-heat-resistant resin to withstand wave soldering temperatures. * **Internal Sealing:** Often includes an internal O-ring or epoxy seal at the base to prevent flux contamination during soldering. --- ## 3. Terminal Layout (DPDT) Since this is a **DPDT** switch, it features 6 terminals organized into two columns. ### Pin Functionality | Pin Number | Function | | :--- | :--- | | **1 & 4** | Normally Closed (NC) | | **2 & 5** | Common (COM) | | **3 & 6** | Normally Open (NO) | *In the **ON-ON** configuration, flipping the lever connects Pin 2 to Pin 1 (and 5 to 4) in one position, and Pin 2 to Pin 3 (and 5 to 6) in the other.* --- ## 4. Application Examples 1. **Industrial Control Panels:** Used for mode selection (Auto/Manual). 2. **Telecommunications:** Signal routing on rack-mounted blades. 3. **Medical Equipment:** Power or function toggles on handheld devices. 4. **Test & Measurement:** Switching between different measurement ranges or inputs. ---
