Introduction

A rotary switch, such as the 42A36-02-1-02N, is an electric switch used in a variety of applications to control the flow of energy from one source to another. Rotary switches allow for the user to select from multiple positions, and make contact between two or more terminals for a variety of purposes. The underlying premise behind their successful operation is the ability to make and break multiple circuit connections through a common rotary motion.

Design Basics of a Rotary Switch

Generally, a rotary switch consists of a cylindrical shaft which supports one or multiple external contacts, and internal contacts which are connected to a stationary circuit board. The cylinder is usually mounted within a housing, which serves to protect the contact mechanisms from external influences that may interfere with the switch.

As the shaft is rotated within the housing, it makes contact with the external contacts mounted on the outside of the housing. This in turn causes the internal contact points to "open and close" in a jogging manner, effectively linking separate circuits and thus allowing current to flow through the desired path.

42A36-02-1-02N\'s Application Field and Working Principle

The specific features that make the 42A36-02-1-02N rotary switch suitable for many different applications are:

• It is a three-position switch, with a rating of 120A at 600VAC, and 120ADC at 100V.
• It comes with dual fixing screws, making installation quicker and easier.
• It is highly resistant to corrosion and extreme temperatures, making it suitable for use in a variety of environmental conditions.
• It is fully insulated and flame-retardant, and is UL and CSA approved.
• It features a short-circuit stop mechanism, which ensures that contacts are disconnected at the correct position.

As outlined previously, the working principle of the 47A36-02-1-02N rotary switch is a "make and break" contact operation. That is, when the shaft is rotated, it creates contact with the external contacts, thus connecting or disconnecting the internal contacts and closing or opening the circuit.

The specific features of the 47A36-02-1-02N make it suitable for a variety of applications, including HVAC, mining, lighting, and industrial applications.

Conclusion

Rotary switches, such as the 47A36-02-1-02N, are extensively used in applications for which reliable and safe switching is required. Their core design relies on the ability to make and break multiple circuit connections through a common rotary motion, thus allowing for controlled and efficient distribution of energy from one source to another.

The 47A36-02-1-02N rotary switch is designed for excellent reliability and performance, and is resistant to harsh environments. Its use has been proven in a variety of applications, such as HVAC, mining, lighting, and industrial applications.
