Our exposure hand switches at Newheek are categorized by the number of their positions. There are currently three main types: one, two, and three. Today, I will mainly talk about the 2-position exposure handbrake switch. The meaning of the two-speed switch is that the first stage is the preparation state, and the second stage is to control the exposure to radiation. Do you know why there are two gears? Let me give you a very clear simple example. If there is only one gear, the doctor may trigger it by mistake, resulting in the generation of radiation and ionizing radiation, which will be harmful to the human body if it is operated for a long time. If the exposure hand brake switch is designed with two gears, the probability of false triggering will be greatly reduced. The other is to set two gears to play the role of reminder and preparation: for example, when the doctor is preparing to take a film, he will tell the patient how to position the patient. When the exposure begins, the doctor will ask the patient if they are ready, and the filming will begin. At that time, the doctor will press the first gear to make the tube warm up and enter the ready state. If he finds that the patient’s position is not suitable, he will not press the second gear again until the adjustment meets the requirements and press the second gear. After talking here, I believe everyone has a clearer understanding of why the high-power X-ray machine exposure handbrake is set to 2nd gear. Regarding the composition and structure of the exposure hand brake switch, from the appearance point of view, it is mainly divided into: handle, base, spring wire and connecting plug. 2 gears are mainly divided into 3-core and 4-core specifications. The lengths of spring wire are 3m, 6m and 10m. If there are special requirements, our company can accept customization.
