Whether the hand brake and x ray foot switch can be installed on the X-ray machine at the same time is determined by the type of X-ray machine. The hand brake switch is installed on the X-ray machine. Its function is to control the exposure of the film. The foot activated switch is installed on the X-ray machine. Its function is to control the perspective of the X-ray machine. With the development of modern medicine, X-ray machines are not only used for photography or fluoroscopy, but also for multi-purpose use, such as C-arm X-ray machines and UC-arm X-ray machines. These two X-ray machines can be used for both perspective and photography. On this basis, both hand brake and foot activated switch can be used in C-arm and UC-arm, so hand brake switch and foot activated switch can be applied to X-ray machine at the same time.
