The three operating buttons in the temporary box are typically labeled as "Up," "Down," and "Run." This labeling is straightforward and directly corresponds to the basic actions that an operator needs to perform when controlling equipment like lifts or elevators.

"Up" and "Down" are intuitive labels for buttons that would control the vertical movement of a device, indicating the direction of motion. "Run" signifies the action of activating the equipment to operate, which is particularly useful in situations where continuous operation is needed until another action is taken, such as stopping the device.

This nomenclature is widely recognized in the industry for simplicity and ease of use, allowing quick understanding and operation, especially in high-pressure situations where clarity in function is critical. The other options utilize terminologies that do not correspond as directly to general equipment operation or might imply more complex functions that are not indicated in a temporary operating context.
