What switch must be depressed to use the drive stun feature without deploying probes?

The correct choice is the ARC Switch. This switch is specifically designed to activate the drive stun feature on the Taser 7 without the need for deploying probes. Drive stun functions by making direct contact with the target using the device, allowing for immediate control or compliance without the long-range effect of the probes.

When the ARC Switch is engaged, it sends an electrical charge directly through the contacts of the Taser, enabling the user to incapacitate a subject in close proximity effectively. This feature is often essential in situations where a deployment of projectiles is not practical or necessary, allowing for a versatile response according to the tactical situation.

Other functions, such as the safety switch, trigger, and battery pack release switch, serve different roles within the operation of the device. The safety switch is meant to prevent accidental discharge, the trigger is used to deploy the device in its primary function, and the battery pack release switch is to change or remove the power source. Each of these has its specific purpose and does not directly influence the ability to utilize the drive stun feature.
