Touch switch related circuits
The speed of the moving contact before and after switching on of the switch with light touch switch has a vital influence on the switching performance. Therefore, the detection of stroke time characteristics of high-voltage switches is an important part of high-voltage switch detection.
Because the switching contacts move in a straight line, an attachment moving with the moving contacts can be installed. When the moving contacts are divided and closed, the attachment moves in a straight line with the connecting rod. Through the photoelectric sensor, the continuously varying displacement can be changed into a series of electrical pulse signals.
It is also the basis for calculating the high voltage switch and closing speed.
In the control circuit of the current loop, the current amplifier usually chooses a larger gain. The advantage of the current amplifier is that it can select a smaller resistance to obtain enough detection voltage, and the detection resistance has a small loss.
High-voltage switch on-off speed, especially the number of the pulse, can realize the measurement of the whole travel parameters of the moving contact; at the same time, record the time value of each electric pulse, divide the displacement by the time, can calculate the maximum speed and average speed of the moving contact in the process of motion.
Light touch switch with lamp has the advantages of small contact resistance charge, accurate operating force error, diversification of specifications and so on. Because light-touch switches are used for environmental conditions (pressure less than twice the elasticity / ambient temperature and humidity conditions and electrical performance) large equipment and high-load buttons are replaced directly by conductive rubber or metal fragments of pot switches, such as medical equipment, television remote controls, etc.
