For electrically-driven equipment, how must the footswitch be positioned to allow operation?

In the context of electrically-driven equipment, the footswitch serves as a control mechanism that initiates the operation of the machinery. For it to function correctly, the footswitch must be depressed. When the footswitch is pressed down, it completes the electrical circuit, allowing power to flow to the equipment and enabling it to operate.

The requirement for the footswitch to be depressed is a standard design feature in many electrical systems, providing a hands-free way to control machinery while ensuring that the operator is engaged and aware of the equipment's operation. This design enhances safety since the machine operates only when the operator actively engages the footswitch, preventing unintended activation.

In contrast, if the footswitch is released, turned, or blocked, it cannot complete the circuit, and the equipment will not operate. These other positions do not provide the necessary input for activation, which is why they do not meet the requirement for the proper functioning of the equipment. Thus, the correct operation of the footswitch is crucial in facilitating the safe and efficient use of electrically-driven equipment.
