### 2. Electronic Contact Block
The "brains" of the component is the contact block attached to the back of the operator.
* **Contact Arrangement:** The "10" in the part number indicates a **1NO** configuration. When the button is pressed, the circuit closes; when released, it opens.
* **Voltage/Current Rating:** These units are typically rated for heavy-duty industrial use:
* **AC:** Up to 600V (depending on insulation) / 10A (thermal current).
* **DC:** Typically 110V/2.2A or 220V/1.1A.
* **Terminal Type:** It uses M3.5 screw terminals with captive wire clamps, allowing for easy wiring with ring or spade lugs.

### 3. Mechanical & Structural Components
The AOFW210-R is built to withstand harsh environments (IP65 rated).
#### A. The Operator (The Red Button)
The button itself is made of durable plastic. The "Flush" design means the button sits nearly level with the bezel, preventing accidental activation from side impact.
#### B. The Bezel and Housing
* **Locking Ring:** A metallic or high-strength plastic nut that secures the unit to the panel.
* **Gasket:** A rubber seal that ensures moisture and dust do not enter the control panel (meeting NEMA 4X/13 and IP65 standards).
#### C. Return Spring
A high-tension internal spring provides tactile feedback and ensures the button returns to its original position immediately after being released (Momentary action).
