The exposure hand switches produced by our Newheek are classified according to product grades. There are currently three main types: one gear, two gear and third gear. Today I will mainly explain the two-speed exposure hand switch.
As the name implies, the exposure hand switch of two gears is pressed to the second level of exposure. The first stage is the exposure preparation stage, and the second stage is the exposure state. Do you know why you want to set the exposure in two levels? Let me give you a simple example and you will see it at a glance.
If there is only one gear, the doctor may unconsciously put the exposure hand switch in his pocket after taking out the film. At this time, if you accidentally touch the button, it is easy to cause exposure, and exposure will inevitably produce x-rays. If there are such mistakes for a long time, it is harmful to the human body. If the exposure hand switch has two gears, the probability of triggering this exposure will be greatly reduced.
The other is the exposure hand switch setting two gears, which serves as a reminder and preparation: for example, the doctor will tell the patient how to locate the patient when taking a film. When the exposure begins, the doctor will ask the patient if he is ready and start the exposure. At this time, the doctor will press a gear to make it in a ready state. If he finds that the patient’s position is not appropriate, he will not press the second gear again, thus reducing the x-ray dose.
Seeing this, I believe everyone has a clearer understanding of the setting of the two-speed manual switch. Regarding the composition structure of the exposure hand switch, from the appearance point of view, it is mainly divided into: handle, base, spring wire, and connector. The two-speed exposure hand switch is mainly divided into 3-core and 4-core. The length of the spring wire is 3 meters, 6 meters, and 10 meters.
