Which power tool requires a constant pressure switch EXCEPT?

• A. Percussion tools
• B. Chain saws
• C. Routers
• D. Circular saws

Answer: (C)

A constant pressure switch means the tool only runs while you’re actively pressing the control; release it and the tool stops. This safety feature is common on many handheld power tools to prevent accidental starts. Routers are the exception because they typically have an on/off switch with a lock-on option, allowing the tool to run continuously without needing to keep pressure on the trigger. You can start it, engage the lock, and let it run until you deliberately switch it off. Per percussion tools, chain saws, and circular saws usually require you to keep pressing the trigger (or throttle) to continue operating; releasing the switch stops the action. That’s why they are described as needing a constant pressure switch.
