Rotary Switches are a type of electrical switch used in a range of applications. The 71MB30-02-1-10S is a rotary switch designed for specific uses, such as controlling circuits and providing single-pulse output. This article will discuss the application field and working principle of the 71MB30-02-1-10S rotary switch.

The 71MB30-02-1-10S rotary switch is a type of 10-position switch. Its application field covers a wide range of industries, including industrial controls, medical equipment, military and aerospace, and consumer electronics. The switch is used in equipment that requires switching from one system to another, such as circuit protection systems, electrical control panels, and motor control circuits. It is also suitable for use in commercial appliances, automotive applications, automated machinery, and test equipment.

The switch is composed of a rotary actuator and a printed circuit board. It provides 10 positions of switching: clockwise, counterclockwise, and spring return. Each position has a unique output that can be used to control various functions, such as voltage selection, current regulation, and logic control. The switch is operated manually by rotating the actuator or automatically by actuating the switch.

The working principle of the 71MB30-02-1-10S rotary switch is based on two primary components: the actuator and the printed circuit board. The actuator consists of two elements: a wedge-shaped rotor and a spring. The rotor is connected to a set of contact points and can rotate within the printed circuit board. As the rotor moves, it causes the contact points to make and break electrical connections, thus opening and closing the switch.

The switch is designed to be durable and reliable, with a long service life. It is dustproof and resistant to high humidity and temperatures, up to 80°C. For added protection, the actuator is sealed to prevent dirt and moisture from entering the switch. The switch is also designed to have low contact resistance, with a maximum of 30 milliohms.

The 71MB30-02-1-10S rotary switch is a durable, multi-purpose switch suitable for a variety of applications. Its wide range of functions enables it to be used in many industries, from industrial to military and aerospace. It can provide 10 positions of switching and low contact resistance, making it suitable for use in high-temperature and difficult-to-access environments.
