Rotary switches, such as the 71MAS30-02B09S model, are used to connect and disconnect circuits by using rotary motion. They are used in a wide range of applications, from industrial and military settings to consumer electronics. This article will explore the application field and working principle of the 71MAS30-02B09S rotary switch.

Application Field of the 71MAS30-02B09S Switch

The 71MAS30-02B09S is a rotary switch constructed with a full metal body, nickel-plated contacts, and a high-temperature range of operation. This switch is ideal for applications in a wide range of low and medium power applications, including automotive, computer, telecom and industrial control systems. It is also suitable for both digital and analog applications and can be used as a control element in devices ranging from simple beepers to complex digital and analog control systems.

The 71MAS30-02B09S is a fully sealed switch with a 10A contact rating. It is designed for a long service life, and its corrosion-resistant contacts ensure reliable operation even in harsh or moisture-rich environments. The contacts are divided into two separate pairs and can be configured for both momentary and latching operations. The switch also offers a range of mounting options, including surface-mount and radiator mounting.

Working Principle of the 71MAS30-02B09S Switch

The rotary switch works on the principle of electrical induction. When two electrical components, such as two wires, are brought into contact with each other, the electrical charge between them induces current in the other wire. This current is then transformed into an electrical signal, which is then used to control the switching operation. This switch works in the same way, but instead of contact with two separate wires, the contacts are arranged in a circular fashion and respond to the rotation of the switch.

The circuit configuration of the 71MAS30-02B09S allows for both single pole and double pole applications. In a single pole application, a single contact pair is connected to the power supply and output path. In a double pole application, two contact pairs are connected to two separate paths, one for the power and one for the output. Depending on the switch configuration, either one or both of the contact pairs can be used to turn the switch ON or OFF.

The switch is designed to be operated with a minimum of effort from the user. This can be exemplified by using the 71MAS30-02B09S switch in a simple momentary circuit. To operate the switch, the user simply turns the switch until it reaches the desired position. The switch then delivers the signal to the output, completing the circuit and activating the desired operation.

Conclusion

The 71MAS30-02B09S is an excellent rotary switch designed for ease of use and long life in any environment. With its two contact pairs, this switch is well-suited for both digital and analog applications, including industrial and consumer electronics. The switch operates on the principle of electrical induction; the moving contacts cause a current to flow, which is then transformed into the desired electrical signal. With its corrosion-resistant contacts and 10A contact rating, the 71MAS30-02B09S is a highly reliable rotary switch designed for reliable operation in any environment.
