CPMD isolation switch screw - Using impact drivers on screws into plastic and metal can have several drawbacks



The CPMD isolation switch cannot be operated without the securing screw into the base being fitted. 


IMPORTANT: When putting the screw back in, don’t tighten it too much or you may break the switch. 

Use a manual Philips head screwdriver, not an impact driver, because an impact driver can over-tighten and damage the plastic parts.




Using impact drivers on screws into plastic and sheet metal can have several drawbacks:


Some issues to be aware of:


1. Too Much Power: Impact drivers are strong and can easily strip screw heads or damage softer materials like plastic. They’re not the best for delicate jobs.


2. Hard to Control: The hammering action of impact drivers makes it tough to be precise, especially with small or delicate screws.


3. No Torque Control: Unlike drills, impact drivers don’t have an adjustable clutch. This means you can’t fine-tune the torque, which can lead to overtightening and damage.


4. Risk of Cracking: The force from an impact driver can crack or damage materials that are prone to breaking, like certain plastics and thin metals.




For working with plastic and metal, a standard drill with an adjustable clutch is often a better choice to ensure you don’t damage the material or the screws.
