Rotary switches are fixtures used in electrical appliances to select between several circuit options, typically on/off positions. They are usually made of a range of metals and plastics and often have an operating handle or a key that extends out of the device for easy control. The PLR3278 series rotary switch is a stamped, sealed, and reflow-safe switch based on two-stage assembly and lever design. It is a 20-position rotary switch and includes an actuator, a shielding cap, and a flexible contact array.

This rotary switch offers a wide variety of configurations that can be used in a variety of applications. It is typically used in communicating amongst telecommunication equipment, appliances, testing and measuring instruments, audio equipment, and computers. The flexibility of the switch makes it possible to control multiple functions in a circuit, such as the power supply, digital logic, sensors, and other high-voltage systems. It can also be used for switching time delay circuits and for controlling stepper motors.

This series rotary switch is designed to offer reliable performance in high-voltage systems. Its high dielectric strength ensures that it can survive in such a difficult environment and in a range of temperatures. Thanks to its reliable insulation, it can remain sealed for long periods and its metal body is polished for protection against corrosion.

Additionally, this rotary switch has a built-in mechanical locking mechanism that prevents it from rotating against its base. This feature helps ensure that the switch can stay in one position for long periods and is not easily disturbed. Moreover, it includes flexible snap-in terminals that can be adjusted according to the user’s needs.

The working principle of the PLR3278 series rotary switch is fairly simple. When the actuator is rotated, the contact array will make electrical contact with the corresponding terminal. This, in turn, allows the current to flow to other areas of the circuit depending on the positions set by the user. It is important to note that the contact array must be properly insulated to prevent short-circuiting and possible damage to the device.

Overall, the PLR3278 series rotary switch is an ideal choice for a range of applications. Its flexibility, durability, and reliable insulation make it a great choice for controlling multiple functions in a circuit. Additionally, its built-in mechanical locking mechanism ensures that the device can be used in harsh conditions and remain in one position for long periods of time.
