The type and characteristics of the toggle switch are also clearly distinguished when it is used, because the toggle switches used in different equipment are different, so it is necessary to use the toggle switch correctly, and the performance and requirements are clear.
There are many kinds of dial switches. At present, there are mainly two kinds of dial switches widely used. They are decimal input, but the output is different. One is BCD code (i.e. binary-decimal) output, the other is decimal output. As the most convenient decimal input/BCD code output dial switch for man-machine interface. Each dial can represent a decimal number. Several pieces of BCD dial can be selected to splice if several decimal numbers are needed. For example, four pieces of BCD dial can be spliced to get four decimal input dial groups. There are five contacts behind each BCD dial, of which A is the input control line and the other four are the output signal lines of BCD code. When the dial is dialed to different positions, the input control line A is connected to one or more of the four BCD code output lines respectively. The state of the BCD code output line connected by the system coincides with the decimal number indicated by the dial and accords with the binary-decimal coding relationship. The principle of decimal output dial switch is well understood. Each dial has 090 positions, and each position has corresponding digital display, representing the decimal number of dial input. There are 11 contacts behind the dial, of which A is the input control line and the other 10 are the output signal line. When the dial is dialed to different positions, the input control line A is connected to one of the 10 output lines, and only one is connected.
The feature of this product is the use of engineering plastics with good heat resistance and chemical resistance. The standard gold-plated contacts can ensure its reliability and long life, and the contacts can be automatically cleaned when the switch is on and off. At present, the switch is widely used in data processing and communication.
Above is the detailed requirements of the specific type and characteristics of the dial switch. Please understand these problems in detail before use to ensure the normal use of the dial switch.
