Rotary SwitchesRotary switches are electromechanical switches used to make or break electrical circuits. Invented in the late 19th century, rotary switches have been widely used in houses, factories, and commercial buildings into the early 21th century. A rotary switch is a switch consisting of a wheel or disk with cam operated mechanical contacts. The contacts are usually attached to two circular plates divided into multiple pie-shaped sectors of equal size, with a detent or "click" action securing the wheel in positioned on the contacts.44M90-04-1-03N is a type of rotary switch, widely used in fields such as aviation,medical,military and industrial control. It has a wide operational temperature range of -55~105 degree. It is resistant to shock, vibration, and dust and moisture, due to its locking device made of non-magnetic stainless steel. The working principle of 44M90-04-1-03N is relatively simple. It has two contact plates and the rotary wheel. The contact plates are made of silver/nickel alloys which are subjected to a vacuum brazing process, welding them securely to the switch body and ensuring electrical continuity. The contact plates are divided into sectors, with each sector being connected to a set of contacts. When the wheel is rotated, each sector of the contact plate contacts a unique set of contacts. This action enables different circuits to be connected, depending on the position of the wheel.44M90-04-1-03N rotary switch broadly used in next generation 5G telecom base station, special communications system, leading 4K or 8K TV broadcasting service and data transmission around the world. This rotary switch also can be applied in avionics guidance navigation system and aviation control system, which need to ensure reliable operation in a much wider temperature range. The switch can be used in medical equipment and military applications, such as drone control, distance measurement and surveillance, laser weapon system and robotics. In industrial automation, this rotary switch’s reliable performance at more regulated temperatures is ideal for controlling industrial machinery.The rugged and reliable design of 44M90-04-1-03N switch has made it popular with telecom, medical, military, and industrial automation designers. By customizing the operating temperature and contact configuration, it can be quickly adapted for various types of applications. This, alongside its failure-resistant design, makes it an ideal choice for complex, high-tech applications.
