Where is the air compressor switch located on PA4's?

The air compressor switch on a PA4 is located on the #2 end. This positioning is strategic as it provides operators and maintenance personnel easy access to the switch from the ground level when servicing the equipment or during operations. Placing the switch at the #2 end allows for better visibility and convenience, making it easier to monitor and control the air compressor's function in relation to the overall system operations of the PA4.

The other options may suggest locations that are less practical for easy access or visibility. For example, positioning the switch at the front end or rear end could hinder accessibility depending on the setup of the equipment and surrounding areas. Likewise, placing it in the operator's cabin could complicate real-time adjustments while the equipment is in operation, as it separates the control of the air compressor from its physical location in the machinery.
