Rotary Switches

A rotary switch is a type of switch used in a variety of applications. It consists of an array of contacts arranged around a central shaft, with a rotating knob or handle used to move an actuator from one position to another. Rotary switches offer numerous advantages over other switch types, including greater reliability, long life, and the ability to handle high currents and voltages.

The HS16-3 series of rotary switches are designed for heavy-duty industrial applications, including motor control, safety systems, and power distribution. These switches have a shaft-through design, with a rounded profile, and long travel of the actuator. This makes them suitable for applications where precise, repeatable switching is required. They are also durable enough for high-vibration and shock environments, and can handle up to 480V/20A.

The working principle of the HS16-3 rotary switch is fairly simple. When the actuator rotates, it moves a set of contacts across a series of stationary terminals. Depending on the position of the contacts, a connection is made or broken. In other words, the switch switches the current on or off according to the position of the actuator. This allows the switch to control the flow of current in any system.

The HS16-3 rotary switches are commonly used in motor control, safety systems, and power distribution applications. For example, they are often used in elevator control systems, enabling a engineer to switch between pre-programmed speeds to control the movement of the lift. They can also be used in relay control, allowing an engineer to switch electrical relays on or off from a single switch. In addition, these switches are also used to directly control motors, enabling an engineer to easily switch between speeds and torque settings.

In summary, the HS16-3 series of rotary switches are designed for heavy-duty industrial applications. They allow precise, repeatable switching and can handle up to 480V/20A. They are often used in motor control, safety systems, and power distribution applications, and can be used to switch electrical relays on or off from a single switch or directly control motors.
