What is a variable speed trigger in power tools?

A variable speed trigger is a feature that enables the user to control the speed of the power tool by varying the amount of pressure applied to the trigger. This functionality is essential as it allows for greater precision and versatility when operating the tool. For example, when working on different materials or applications, the user might need to increase or decrease the speed to ensure optimal performance and prevent damage to either the tool or the workpiece.

This sensitivity to pressure not only enhances control but also improves safety, as it allows the user to start the tool at a low speed before ramping up as needed. By providing this level of control, the variable speed trigger is a critical component in the design of many power tools, making them more adaptable to various tasks.
