### 2. Breakdown of the Model Number
The suffix codes provide details on the mechanical behavior and aesthetics:
* **M2RT**: Series identifier (30mm Rotary Type).
* **30**: Refers to the **30mm** hole size required for panel mounting.
* **R2**: Indicates a **Round** shape with **2 positions**.
* **N**: Typically signifies the contact block type (Standard "N" type block).

### 3. Electronic & Mechanical Parts
The assembly consists of three primary modules:
#### A. The Operator (Actuator)
The visible part on the front of the panel. It is usually a "Short Lever" or "Knob" style.
* **Material:** Often Chrome-plated zinc or high-impact plastic.
* **Action:** 90-degree throw between Position 1 and Position 2.
#### B. The Contact Block
This is the electrical heart of the switch located behind the panel.
* **Contacts:** Made of silver alloy to reduce electrical resistance and prevent oxidation.
* **Terminals:** Screw-type terminals for secure wire connection (typically supports up to 14 AWG wire).
#### C. The Mounting Collar
A threaded ring or locking mechanism that secures the actuator to the control box.

### 4. Circuit Example
If you are wiring this for a basic motor control or signal light:
```markdown
[Power Source L1] ---- [Terminal 1 (NC)] ---- [Stop Indicator Light]
|
---- [Terminal 3 (NO)] ---- [Motor Starter Coil]
```
* **Position 1:** Terminal 1-2 (Closed) -> Stop Light is ON.
* **Position 2:** Terminal 3-4 (Closed) -> Motor starts.

### 5. Common Applications
* **Manual/Auto Selection:** Switching between manual override and PLC control.
* **Power Isolation:** Simple ON/OFF for low-voltage control circuits.
* **Mode Selection:** Selecting between different speeds or operational cycles in machinery.
