Rotary Switches

Rotary switches are simple devices that are used to make or break electrical connections. They are composed of a rotating knob, knob shaft, and a series of contacts that open or close circuits based on the knob\'s position. This makes them very useful for applications where you need to choose between multiple settings or power sources. They are often used in switches, dimmers, and other related devices, and come in a variety of shapes and sizes.

One type of rotary switch is the MRB12H-BA. This type of switch is designed to control currents up to 12A DC, allowing for a wide range of applications. It features a 1-pole 3-position configuration, which means that it can be wired to three separate circuits. This makes it great for adjusting the power output from lights or appliances.

The MRB12H-BA is designed to operate by a series of physical contacts inside the switch. When the switch is rotated, the contacts line up in different configurations. There is one contact for each of the three possible positions. As the knob rotates, the contacts line up with the other components in the circuit, opening or closing the connection and thus controlling power flow. This type of operation ensures that the switch is reliable and can withstand the load of large currents or the repeated switching of switches.

The MRB12H-BA is well-suited for many applications due to its adjustable settings, excellent durability, and o-ring seal design. Its small size and high-temperature ratings make it suitable for narrow spaces and an ideal choice for harsh environments. Due to its reliable design, it is a popular choice for switches, dimmers, and light fixtures. It can also be used to control electric motors and other equipment that require multiple settings or power sources.

Rotary switches, such as the MRB12H-BA, are a great choice for when you need to control power or choose between different settings. They are reliable, durable, and can be used in a variety of applications. With a bit of knowledge, you can be sure to find the right rotary switch for your needs.
