How close can gate switches be closed on horizontally sliding doors to the strike jamb?

The requirement for gate switches on horizontally sliding doors mandates that they must be positioned at a specified distance from the strike jamb to ensure both safety and proper operation of the door mechanism. Closing the switches too close to the jamb can lead to potential hazards, including false triggering or malfunction of the door's safety features.

Choosing a distance of 2 inches strikes a balance between proximity and safety. This distance minimizes the risk of the switch being activated unintentionally, while still allowing for a responsive functioning of the door's operation. It is crucial for designers and installers to adhere to this standard to maintain an effective safety protocol, preventing accidents related to door operation.

This ensures that the door does not inadvertently close on any obstacles or pedestrians in the closing path, thereby enhancing safety for users. The other distances listed do not align with industry standards, which specify that 2 inches is the optimal distance for gate switches on horizontally sliding doors.
