Rotary Switches

A rotary switch is an electrical switch consisting of a set of inputs connected to a rotating contact on its output axis. The switch can then be rotated to make contact with different outputs, resulting in specific electrical configurations.Rotary switches are typically used where multiple contacts are needed, such as audio selector switches, motion sensing switches, and application-specific switches.

71MA30-01-4-03N Application Field and Working Principle

The 71MA30-01-4-03N is a multi-pole 30-position rotary switch from ACT other. This switch is suitable for various applications, such as panel mounting, power distribution, and circuit switching. This switch is ideal for applications that require setting up various electrical configurations without the need for multiple switches.

The 71MA30-01-4-03N is a single-deck, four-pole rotary switch capable of switching 30 positions. It uses metal-oxide varistor (MOV) technology to protect the switch contacts against electrical transients. The switch has non-interchangeable contacts and operates at a range of temperatures between -25°C and 85°C.

The working principle of the 71MA30-01-4-03N switch is as follows: By rotating the switch shaft, the contacts on the switch deck are mechanically driven. When the contacts touch the contacts of the output axis, a closed circuit is created, allowing current to flow. This completes an electrical configuration. To change the configuration, the switch must be rotated to the desired position.

In addition to its use in electrical circuit switching, the 71MA30-01-4-03N can also be used as a general-purpose switch in a variety of applications, such as medical devices, industrial machinery, and consumer electronics. It is also suitable for use in harsh and wet environments, as it is rated IP66, providing protection against dust and water.
