Rotary Switches

Rotary switches are a type of electrical switch where the flow of electricity can be directed from one point to another by turning a rotary handle or knob. Rotary switches are commonly used in audio systems, electrical power distribution equipment, and general electronics. One of the most notable uses of a rotary switch is to control the phase of alternating current power in the three phase power systems used in electrical motors.

57M22-04B16N

The 57M22-04B16N is a brand specific rotary switch made by the company Finder. It is a multi-pole changeover switch with a maximum of 16 poles. It features a large, ergonomic knob making it suitable for high use environments and allows easy operation in limited space areas. It also has dielectric strength of 1000V, contact protection up to 10A, and an operating temperature range from -25 to +85 degrees Celsius.

Application Field

The 57M22-04B16N can be used in a variety of application fields where multiple discrete positions are needed to control the flow of electricity. A few examples of these applications include:

• Controlling the flow of electricity in audio equipment, such as amplifiers.
• Controlling the flow of electricity in motor control systems.
• Controlling the flow of electricity in relays or electrical circuit breakers.
• Controlling the flow of electricity in multiplexer systems.

Working Principle

The 57M22-04B16N is an isolated contact switch, meaning the contacts are isolated from each other. In operation, the knob is rotated clockwise or counter-clockwise depending on the arrangement of the switch. This causes the rotating cam in the switch to move and actuate the contacts, thus allowing the flow of electricity to be directed from one point to another.

The 57M22-04B16N has a patented self-locking mechanism that keeps the switch in the desired position even if it undergoes vibrations and shocks. This ensures that the switch will not move unexpectedly, providing an additional layer of safety and reliability.

The switch also features a quick-make, quick-break operation which ensures a reliable and safe contact, even at the minimum switch life cycles. This helps to improve the reliability of the switch and also helps to protect against short circuits and overloads.
