Rotary Switches

Rotary switches are a type of electrical switching device. They are used in a variety of applications, ranging from industrial equipment to consumer electronics. In a rotary switch, a shaft is typically rotated a certain number of times to select the desired switch position. The switch may be operated manually, or it may be operated by an external motor or device.

71A30-03-5-02N Application Field and Working Principle

The 71A30-03-5-02N is a multi-pole, 4-position rotary switch rated at 30A and 250V. It is typically used in applications requiring a mechanical method of controlling a circuit, such as motor control, audio systems, lighting, and electrical appliances. The switch has right-angle terminals, and it is suitable for printed circuit board mounting.

The 71A30-03-5-02N has four different positions, which are designated as off, 1, 2, and 3. The pole pieces are held in place by a common locking washer, which helps to ensure that the contact points are securely engaged. When the shaft is rotated, the pole pieces move and make contact with their respective switch contact points, thus allowing current to flow through the circuit in the desired direction.

The switch has a spring-loaded mechanism, which helps to ensure that the shaft is positioned securely and accurately in the desired position. This helps to reduce any wear and tear on the switch contacts. Additionally, the switch has a positive stop feature, which prevents accidental over-rotation and helps to keep the switch in its intended position.

The 71A30-03-5-02N is a reliable switching device which can be used in a variety of applications. It is an economical solution to providing manual control of electrical circuits. The switch is easy to install and operate, and its robust design ensures long-lasting performance.
