Rotary switches are a type of electrical switch that use a rotating “disc” to select various positions. In the case of the MRA112/208, it is a multi-position rotary switch with eight positions and is used to apply AC or DC voltages through connections that are grouped in a star or delta topology. As the disc of the switch rotates, the contacts switch and thus make various connections.

The MRA112/208 has multiple uses and can be used in many applications such as temperature regulation, motor control, switching lights in a multi-light setup or any other sort of switching and controlling of AC or DC circuits. It can also be used for many other types of circuits, such as push button switch and power switches. This rotary switch has a maximum operating temperature of 125°C and is UL-approved.

The working principle of the MRA112/208 is quite simple and straightforward. The internal contacts are firmly held in place by a spring and when the disc is rotated, these contacts move and make different connections as the disc turns. The rotary switch also has an internal protection mechanism, which prevents damage by preventing incorrect wiring.

The MRA112/208 can be connected to devices such as thermostats, relays, or lights to make it easier to switch or control certain circuits. It is also possible to connect a voltage source to the rotary switch, which allows the user to control the voltage of the device they are connecting to the switch. This makes it easier to accurately regulate the amount of electricity that the device is receiving, thus helping to prevent possible damage.

The MRA112/208 has two main types of contacts: normally closed and normally open. The normally closed contacts are the ones that are open when the disc is rotated to their position, but close when rotated away from it. On the other hand, normally open contacts are the ones that are closed when the disc is rotated to their position, but open when rotated away from it. This allows the user to easily switch different circuits without having to manually open or close the contacts.

The MRA112/208 is a great option for those looking for an easy-to-use, reliable and safe way to control or switch electrical circuits. Its robust construction and wide-range of applications make it an ideal choice for a variety of tasks. As well, its simple working principle and versatility make it an ideal solution for those who need a dependable and flexible rotary switch for their home or industrial applications.
