Rotary Switches

Rotary switches play an important role for controlling and selecting circuits. They are widely used when selecting between different electrical circuits.​​​ Different types of rotary switches can be used depending on the desired application. 43A01105S-A02105S rotary switches are commonly used in industrial and commercial applications.

Application Field

The 43A01105S-A02105S rotary switch is widely used in electronic equipment and instrumentation, such as on-off switches, circuit selectors, special applications, lighting and sound control and other electronic equipment that require reliable switching contact operation. It is also used for controlling electrical motors, signal lights and other appliances with electrical circuits.

Working Principle

43A01105S-A02105S switches are mainly composed of an actuator, a base and several sets of contacts. The actuator is installed in the base and connected to the contacts via a common rotating shaft. When the actuator is in a certain angle, it contacts one of the sets of contacts and makes it electrically connected. As showed in the following figure, when the actuator is in neutral position, its contacts are open, so the circuit is open. When the switch is turned clockwise or counterclockwise, it contacts another set of contacts, and thus closes the circuit.

Advantages

The 43A01105S-A02105S rotary switch has the following advantages over traditional switches:

• Ease of use. The switches require less effort to operate than traditional toggle or rocker switches.
• High reliability. These switches are relatively more reliable than traditional switches due to their all-metal construction.
• Long life. These switches have a long service life due to their reliable construction and contacts that are designed to be resistant to wear and tear.

Conclusion

The 43A01105S-A02105S rotary switch is an ideal choice for many applications. It is a great choice if you need a reliable switch with an easy to use design and reliable contacts that are designed to last a long time. This type of switch is great for applications like controlling electrical motors, signal lights and other electrical appliances. With its many advantages, it is no wonder that this type of switch is so widely used in a variety of applications.
