### 2. Internal Electronic Components
While these are mechanical switches, the "electronic" side refers to the contact block and electrical interface:
* **Contact Block:** The heart of the unit. It contains silver or gold-plated contacts to ensure high conductivity and resistance to oxidation.
* **Galvanic Isolation:** The switch provides physical separation between the contacts (Zb form), ensuring that the Normally Open (NO) and Normally Closed (NC) circuits are electrically isolated from each other.
* **Termination:** Screw terminals are used for wiring. These are designed to handle vibration without loosening, a critical factor in industrial environments.

### 3. Functional Operation
The device functions as a **Position Switch**:
1. **Mechanical Input:** An object hits the roller lever (Actuator).
2. **Spring Mechanism:** The internal spring reaches a trip point.
3. **Electrical Output:** The contact bridge moves rapidly (Snap action), opening the NC circuit and closing the NO circuit to signal a PLC or Safety Relay.

### 4. Application Environments
Due to the **CE** marking and the rugged **AS1** housing, these parts are used in:
* **Conveyor Systems:** To detect the presence or position of a pallet.
* **Safety Interlocks:** To ensure a machine guard is closed before the motor starts.
* **Limit Detection:** Preventing mechanical over-travel in CNC machines or cranes.
