Principle of X-ray exposure hand switch: Control the X-ray exposure. There are two switches. Press the first level to prepare for exposure, and press the second level at the same time to complete the exposure.
The working process of X-ray exposure hand switch is divided according to its structure. The first-level X-ray exposure hand switch has only a pair of normally open switches inside, which control the opening and closing of a circuit. When the button is pressed, the X-ray high-voltage circuit is energized to generate high-voltage to generate X-rays. Release When the button of the hand brake is in position, the circuit is disconnected, and X-rays are no longer generated because there is no high-voltage supply. Two pairs of normally open switches are installed in the two-level X-ray exposure hand switch. The contacts of the normally open switch control two circuits respectively. The switch of the first level controls the X-ray machine’s camera to prepare for shooting, so that the X-ray machine is in the pre-exposure state. Turn on a gear button to cancel the start. The contact of the normally open switch controlled by the second gear button position controls the high voltage generating circuit of the X-ray machine to close and generate X-rays. After releasing it, all the above circuits will be cut off.
