4.2 Mounting
- Prepare Panel: Create a 22mm diameter mounting hole in the control panel. Ensure sufficient space behind the panel for the contact block and wiring.
- Insert Switch: Insert the mushroom head and actuator assembly through the front of the panel hole.
- Secure: From the rear of the panel, slide the mounting adapter and then the contact block onto the actuator. Tighten the locking nut to secure the switch firmly to the panel.

4.3 Wiring
- Identify Terminals: The switch features Normally Closed (NC) contacts. These contacts are typically labeled '1' and '2' or 'NC'. When the button is not pressed, the circuit between these terminals is closed. When the button is pressed, the circuit opens.
- Connect Wires: Connect the control circuit wires to the screw terminals on the contact block. Ensure connections are tight and secure to prevent intermittent operation or arcing.
- Verify: Double-check all wiring against your circuit diagram before restoring power.
5. Operating Instructions
The ZB2-BE102C is a latching emergency stop switch with a twist-to-reset mechanism.
- To Activate (Stop): Press the red mushroom head firmly. The button will latch in the depressed position, opening the Normally Closed (NC) contacts and interrupting the control circuit. This action will stop the associated machinery or process.
- To Reset: To restore the circuit, twist the red mushroom head clockwise. The button will release from its latched position and return to its original state, closing the NC contacts and allowing the control circuit to be re-energized.
6. Maintenance
Regular maintenance ensures the reliable operation and longevity of the emergency stop switch.
- Visual Inspection: Periodically inspect the switch for any signs of physical damage, wear, or corrosion. Check for loose connections or damaged wiring.
- Functionality Test: Regularly test the emergency stop function by pressing the button and verifying that the connected equipment stops as intended. Ensure the twist-to-reset mechanism operates smoothly.
- Cleaning: Keep the switch clean and free from dust, dirt, or debris. Use a soft, dry cloth for cleaning. Avoid using harsh chemicals or abrasive materials.
- Contact Integrity: If the switch exhibits intermittent operation, inspect the contact block for signs of arcing or contamination. Replace the contact block if necessary.
7. Troubleshooting
If you encounter issues with your Baomain ZB2-BE102C switch, refer to the following troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| Switch does not activate (stop) when pressed. | Mechanical obstruction, damaged actuator, incorrect wiring. | Check for obstructions. Inspect actuator for damage. Verify wiring to NC contacts. |
| Switch does not reset after twisting. | Latching mechanism jammed, internal damage. | Ensure full twist motion. If still stuck, replace the switch. |
| Intermittent operation or unreliable contact. | Loose wiring connections, dirty contacts, worn contact block. | Tighten all screw terminals. Clean contacts if accessible. Replace contact block if worn. |
| No power to controlled device after reset. | External circuit fault, power supply issue, other safety devices active. | Check power supply. Inspect other components in the control circuit. |
