Rotary switches are a type of electrical switch which is operated by rotating a shaft or cylinder. They typically have several input contacts, or “poles”, which are connected to a common output contact. As the shaft or cylinder is rotated, the output contact moves from one pole to the next, allowing for the selection of one or more poles. One of the most popular varieties of rotary switches is the MRK112-CE.The MRK112-CE is a nine-pole rotary switch, meaning it has nine input contacts, which are connected to a single common output. It has a built-in self-cleaning mechanism, which automatically removes dirt and other accumulations from the internal contacts. This makes it an ideal choice for applications which may be subject to airborne particles and other contaminants.The MRK112-CE is also designed to minimize mechanical wear and noise, making it an ideal choice for applications where there is a need for quiet operation. Additionally, it is designed to be very reliable, with mechanical contact life of up to 10 million operations and electrical contact life of up to 100,000 operations.The MRK112-CE has a number of different applications. It can be used for selecting one of two or more circuits in any given application, or for selecting one or more inputs in a circuit. Some common applications include lighting controls, sound amplification, audio mixing, and elevator controls.The working principle of the MRK112-CE is fairly simple. As the shaft or cylinder is rotated, the contacts inside the switch move from one pole to the next, making an electrical connection between the selected poles. When the shaft is rotated back to its original position, the contacts will return to their original positions, breaking the connection.The MRK112-CE is a reliable and well-designed rotary switch which is suitable for a wide variety of applications. Its automatic self-cleaning mechanism makes it an ideal choice for applications which may be exposed to dirt and other contaminants. Additionally, its quiet operation and long life makes it a valuable tool for those looking for a reliable rotary switch.
