### 2. Electronic Components & Contacts
The "Electronic" side of this device refers primarily to the **Contact Block** assembly located at the rear of the switch.
* **Contact Configuration (BA-R2):**
* **B:** Standard contact block mounting.
* **A:** 1a1b configuration (1 Normally Open + 1 Normally Closed).
* **R2:** Color coding (Red) and specific revision/mounting style.
* **Wiping Action:** The contacts usually feature a sliding/wiping mechanism to clear oxidation each time the button is pressed, ensuring high electrical reliability.
* **Terminal Type:** Screw terminals are standard, allowing for secure wiring of 14–22 AWG cables.

### 3. Mechanical & Environmental Characteristics
Industrial switches must withstand harsh environments. The M2PH series typically includes:
* **Durability:**
* *Mechanical Life:* ~1,000,000 operations.
* *Electrical Life:* ~100,000 operations at full load.
* **Protection Rating:** Usually **IP65** (Dust-tight and protected against water jets), provided the rubber gasket is installed correctly.
* **Material:** High-impact plastic and copper alloy contacts with silver plating for conductivity.
