Question

which type of switch will shut off the tool when the user releases it? constant pressure switch positive on/off switch double insulated switch ground fault switch

Explanation:

A constant - pressure switch requires continuous pressure (such as a user holding it down) to keep the tool on. When the user releases it (pressure is removed), the switch shuts off the tool. A positive on/off switch is just a regular switch that stays in the on or off position until manually toggled. A double - insulated switch refers to insulation properties (related to safety from electric shock, not the on/off mechanism based on user release). A ground - fault switch is for detecting electrical faults (like a ground fault circuit interrupter) and cutting off power in case of a fault, not based on user release.

Answer:

Constant pressure switch
