Instructions:

1. Handling and Installation:

   • Handle the switch carefully to avoid damaging the actuator or terminals.
   • Ensure the switch is securely mounted to the PCB using the provided solder lugs.
   • Apply the recommended operating force (200 卤 50 gF) to actuate the switch.

2. Soldering:

   • Preheat the PCB to reduce thermal shock.
   • Use a soldering iron with a temperature setting of 350掳C (662掳F) or less.
   • Solder the terminals quickly to avoid overheating the switch.
   • Allow the solder joints to cool naturally without moving the switch.

3. Testing:

   • After installation, test the switch to ensure proper functionality.
   • Verify that the contact resistance is within the specified range (100 m惟 max).
   • Check the insulation resistance to ensure it meets the minimum requirement (100 M惟 min).

4. Environmental Considerations:

   • Store the switch in a dry, temperature-controlled environment.
   • Avoid exposing the switch to extreme temperatures outside the specified ranges.
   • Protect the switch from moisture, dust, and other contaminants.

5. Maintenance:

   • Regularly inspect the switch for signs of wear or damage.
   • Clean the switch using a soft, dry cloth if necessary.
   • Replace the switch if it shows any signs of malfunction or if it has reached its mechanical life limit (100,000 cycles).
