Hand-held power tools must be equipped with what type of switch?

Hand-held power tools must be equipped with a constant pressure switch to ensure user safety and effective operation. This type of switch requires the operator to maintain pressure on the switch for the tool to operate, which helps prevent accidental activation. If the operator's grip is released, the tool will stop running, significantly reducing the risk of injury. The consistent requirement for pressure also allows for more precise control during use, making it safer for various tasks.

Other types of switches, like a toggle switch or rotary switch, do not inherently provide this safety feature, as they can remain in the "on" position if activated, potentially leading to hazardous situations. A manual switch is a broader term that may not specifically refer to the safety features necessary for hand-held tools.
