Rotary Switches

Rotary switches are a type of electrical switch that enable rotation of a contact arm to enable different circuits and connections. The 71BSF36-06-1-09S is an example of a commonly used rotary switch. It is cylindrical in shape and has 9 positions in 90 degrees (a 9-position switch). It has both a common and make contact, and can be used to switch a wide range of electric currents. This type of switch produces a tactile “click” when rotated to a stop.

Applications

This type of switch is applicable for a variety of applications including circuit switching, level matching and volume control. It is a useful tool for instrument-based applications, such as audio and hearing aid devices, electric guitars, and tone generating devices. It is also used in electric-furnace and heating controls. In automation, rotary switches are also applied, which are typically used as pulse inputs to counters or other automated systems.

Working Principle

The 71BSF36-06-1-09S rotary switch is based on a basic principle of switch operation: when the contact arm is rotated, it makes an electrical connection between the common and the make contact. This can be used to switch between different circuit connections for a number of functions. For example, when the contact arm is rotated to each position, it can switch between different resistors, allowing for a variety of volume levels or sound ranges. Alternatively, when the contact arm is rotated, it can switch between different circuits. This is useful for level-matching circuits or even changing the frequency of a tone-generating device.

Construction

The construction of the 71BSF36-06-1-09S rotary switch is a combination of brass, steel and plastic. The body is made of brass, which provides a durable and reliable base. Steel is used to make the contact arms, which ensures a secure and consistent electrical connection. The handle is made of a plastic material, providing an easy grip and more accurate switching. The entire assembly is then held together by a set of screws.

Contact Challenges

Rotary switches have some of the same challenges as other types of switches. They must be regularly inspected for loose or frayed contacts, corrosion, and other signs of wear or misuse. Additionally, contacts must be regularly cleaned and lubricated in order to maintain a reliable connection. It is important to note that many rotary switches only last for a certain number of cycles and eventually need to be replaced.

Conclusion

The 71BSF36-06-1-09S rotary switch is a versatile tool for switching between different circuits or levels. It is simple, durable and reliable, making it a popular choice for many applications. However, it must be kept in good condition, and may need to be replaced after a certain amount of use. With careful maintenance and regular inspections, this type of switch can be an effective and reliable addition to any project.
