### 2. Key Electronic Components & Materials
The device consists of several critical internal and external parts:
* **Actuator (Button):** The plastic part that the user presses. In the "R" series, this is often a rectangular rocker.
* **Housing:** Made of heat-resistant thermoplastic (UL 94V-2 or higher) to prevent melting during high-current operation.
* **Stationary Contacts:** Fixed metal plates inside the switch that connect to the external terminals.
* **Moving Contacts (Movable Arm):** A spring-loaded copper or brass leaf that "rocks" back and forth to bridge the gap between stationary contacts.
* **Contact Points:** Often plated with **Silver (Ag)** or a silver alloy to ensure low contact resistance and prevent oxidation.

### 3. Circuit Configuration: DPST
The "322" designation often implies a **Double Pole, Single Throw** configuration.
* **Double Pole (DP):** It controls two separate circuits simultaneously.
* **Single Throw (ST):** It has only two positions: **ON** and **OFF**.
* **Application:** This is commonly used to disconnect both the "Live" and "Neutral" wires in an AC circuit for safety.

### 4. Dimensional and Mounting Features
* **Snap-in Mounting:** The "R" suffix often refers to the rectangular shape designed to snap into a pre-cut hole in a metal or plastic panel without the need for screws.
* **Terminals:** Usually 6.3mm (1/4 inch) spade terminals, allowing for easy connection via crimp connectors.
