Newheek’s hand switches are classified according to their gear positions. There are currently three main types: one gear, two gears, and third gear. Today, I will mainly explain the two-stage hand brake switch. The two-stage is just two stages, as the name suggests, the first stage is the exposure preparation stage and the second stage is the exposure completion.
Do you know why two gears are set? Let me give you a simple example that is very clear. If there is only one gear, the doctor may unconsciously put the hand switch in his pocket after taking the film. At this time, if you accidentally touch the gear It is easy to cause exposure, and the exposure will definitely produce X-rays. If it is operated for a long time, it will be harmful to the human body. If the hand switch has two positions, the probability of triggering this exposure is Will be greatly reduced.
Another is to set two gears to play the role of reminder and preparation: for example, when the doctor is taking a film, he will tell the patient how to position the patient. When the exposure starts, the doctor will ask the patient if he is ready and start the film. At that time, the doctor will press the first gear to be in the ready state. If he sees that the patient’s position is not suitable, he will not press the second gear again, which reduces the X-ray dose.
Seeing this, I believe everyone has a clearer understanding of why the two-speed hand switch is set.
Regarding the composition structure of the hand switch, from the appearance point of view, it is mainly divided into: handle, base, spring wire, and connector. The two-speed hand brake switch is mainly divided into 3 cores and 4 cores. The length of the spring wire is 3 meters, 6 meters, and 10 meters.
