Rotary switches are an electrical component that often play a key role in controlling and regulating electrical current in applications ranging from commercial manufacturing to residential home wiring. This article takes a look at the 42M36-01-2-05S Rotary Switch and its application fields and working principles.

Overview

The 42M36-01-2-05S is a 12-position, Center-Off type Rotary Switch, operating at 24 VDC. It is UL Listed, CQC certified, has panel or PCB mounting option, and can handle up to 10 Amps of load current. It also has a touch-proof shaft connection.

Rotary switches are used in multiple industrial and commercial applications in conjunction with other electrical components such as relays, contactors, and Circuit Breakers. When designed with multiple poles, Contact Blocks, and Auxiliary Contacts, a Rotary Switch can be used as a series of simple on/off connections, or a more complex selector switch. An example of such an application is seen in motor control applications, where a Rotary Switch is combined with a Contact Block in order to provide quick and easy motor overall control.

Rotary switches are also used in residential wiring applications, such as ceiling fans, light switches, and wall outlets. The same principle applies; a simple on/off connection, or more complex series of connections.

Application Fields and Working Principle of the 42M36-01-2-05S Rotary Switch

The 42M36-01-2-05S Rotary Switch is most commonly used in industrial process control and electrical products. Its application fields include Robotic Automation, Testing Equipment, Industrial Controls, Lighting Control, Printed Circuit Board Assembly, Elevator Control, and Heavy Duty Machinery Control.

The 42M36-01-2-05S Rotary Switch is designed with an off-center center axis and multiple segmented contacts; rotating the knob aligns the contacts with the wiper arm connected to the shaft, thus forming the desired circuit connection. Depending on the type of rotary switch, up to 3, 8, or even 12 different positions may be available.

In addition, the 42M36-01-2-05S Rotary Switch also can be customized with multiple poles, Contact Blocks, and Auxiliary Contacts, which allows it to be used as a selector switch where more than a simple on/off connection is required. To increase the available poles and contacts, a double-pole/double-throw switch can be used, allowing up to four separate switch contacts.

Finally, the 42M36-01-2-05S Rotary Switch has an IP20 degree of protection from dust and foreign material, and a fire-proof reinforced plastic case which enables it to be used for higher current applications. As it is UL Listed and CQC Certified, it is also suitable for use in high-end applications.

Conclusion

In conclusion, the 42M36-01-2-05S Rotary Switch is a versatile electrical component that can be used in both industrial and residential applications. It provides reliable and efficient current control, and can easily be customized to provide multiple poles and contacts for more complicated circuit connections.
