Rotary switches are a type of switch commonly used to provide multiple selection options with minimal space consumption. They consist of an insulated stem which supports a number of metal or plastic knobs or buttons, each of which can be rotated clockwise or counterclockwise to make an electrical connection. In addition, the stem can be moved up or down to one of several settings, thus providing a multi-position or multi-directional selection capability.

The 71MB30-01-4-03S is a type of rotary switch specifically designed for high-current applications. This switch is equipped with four metal rotary knobs and a 25-position stem which can be adjusted to make the desired connection. Each knob is mounted on plastic insulators to ensure that no short circuits occur due to contact with the frame. The device is intended for use in applications where up to 30 Amps of current is required.

The working principle of the 71MB30-01-4-03S rotary switch is quite simple. When the user rotates one of the four knobs, it physically lifts the contacts from the terminal strips, thus interrupting or making the desired connection. When the knob is moved back to its original position, the contacts close again and the connection is restored. The 25-position stem works in a similar manner, except that it enables the user to make multiple connections at the same time, thus providing a multi-position or multi-direction selection capability.

The 71MB30-01-4-03S rotary switch is used in a variety of applications, ranging from industrial automation to home automation and security systems. It is especially well suited for use in high-current applications, such as motor control, power switching, and lamps. Additionally, it provides a simple, cost-effective solution for creating complex switching patterns in applications where space is limited.
