Which of the following is a recommended location for door opening switches?

The recommended location for door opening switches being on the outside arc of the door is advantageous because it ensures that the switch is easily accessible when someone is approaching the door. This placement allows users to activate the switch to open the door without having to reach around or navigate around the door, which enhances accessibility. Furthermore, positioning the switch outside the arc minimizes the risk of accidental activation when the door is in motion, ensuring safety as well.

Door opening switches that are located inside the room may not be as practical, as they would require the individual to already be inside to use the switch, which defeats the purpose of providing a means to easily open the door from the outside. Similarly, locating the switch on a side wall could lead to accessibility issues, as it may not align with the natural approach to the door. Placing the switch above the door frame may also complicate reachability, particularly for individuals with mobility challenges.

Therefore, the location on the outside arc of the door is optimal for safety, accessibility, and functionality, meeting recognized standards for door control in various settings.
