A Door Release Button, also known as a Door Release Switch or Door Release Exit Button, is a device used to remotely unlock or release an electronically controlled door. It is typically connected to an access control or door entry system and allows authorized individuals to exit a secured area without requiring physical keys or access cards.

When someone presses the Door Release Button, it sends an electrical signal to the access control system, which then triggers the door lock to temporarily release or unlock. This action allows the door to be opened from the inside, facilitating a smooth exit for authorized personnel.

Door Release Buttons are commonly used in conjunction with electric locks, electromagnetic locks, or other electronic locking mechanisms. They are preva1ent in commercial buildings, office complexes, residential complexes, hospitals, schools, and any other location where controlled access is necessary.

The purpose of a Door Release Button is to enhance security and provide a convenient and secure means of exit for authorized individuals, while still maintaining controlled access to the building or restricted area.
