The rotary switch is a commonly used switch in electrical control circuits. The circuit can be cut off or connected by rotating the switch. In electrical drawings, the symbols of the rotary switch are usually represented by some abbreviations. The meaning and use of these symbols will be introduced in detail below.
1. S: represents the rotary switch, which is often used in control circuits.
2. M: represents the rotary switch, but is used in motor control circuits.
3. L: represents the light switch, which is often used in control light circuits.
4. F: represents the fan switch, which is often used in fan control circuits.
5. T: represents the clock switch, which is often used in control clock circuits.
6. +: represents the positive pole, which can be used to connect the positive pole of the power supply.
7. -: represents the negative pole, which can be used to connect the negative pole of the power supply.
8. A: represents the switch state, A represents the switch is open, and B represents the switch is closed.
9. B: represents the switch state, A represents the switch is open, and B represents the switch is closed.
10. E: represents the enable signal switch, which is often used in controlling electrical devices.
The above are the commonly used electrical symbol abbreviations and their meanings for knob switches. When designing electrical control circuits, the correct understanding and application of these symbols is very important, which can effectively improve the reliability and stability of electrical control circuits and reduce the possibility of failures.
