Rotary switches are widely used for many applications such as allowing electrical flow between multiple circuits. The 59HS18-05A20S is a hermetically sealed rotary switch, with a life expectancy of more than 10 million operations, making it suitable for a variety of industrial, commercial and military applications.

Application Field

The 59HS18-05A20S is engineered to be a reliable and cost-efficient rotary switch solution for medium to high current usage. It offers high electrical performance over a wide temperature range (-55 to +125°C). This allows it to be used in applications such as switching of loudspeaker systems, lighting, alarms and quiet fans, motor-speed controllers, harmonic reducers, dimmers, and AC power controllers. It is also suitable for double throw switching in office automated systems, instrumentation and radio-communication systems.

Working Principle

The switch is operated by a cam or wheel which turns over a fixed range of motion. This provides a set of poles for the contacts which are controlled by the rotation of the wheel. As the wheel is rotated from one post to another, the contacts open and close. The switch can be switched from one position to another, or from one contact to another.

The switches come in various shapes and sizes, with a wide range of electrical and environmental ratings. The 59HS18-05A20S features a maximum voltage rating of 600VAC@38A, and a maximum current rating of 20A. It also features an arc clearance of 10mm and an insulation resistance of more than 10 megohms.

When in use, the 59HS18-05A20S can handle high volume switching with a small package size and extended life. It is self cleaning, durable and dust tight.

Conclusion

The 59HS18-05A20S is a rotary switch with many applications. It is designed for medium to high current usage and can handle high volume switching with a small package size and extended life. It offers high electrical performance over a wide temperature range (-55 to +125°C). This versatile switch is a cost-efficient solution for many industrial and commercial applications.
