Introduction to Rotary Switches

Rotary switches are an important type of electrical equipment. They are composed of multiple contacts with different electrical properties, and are essential components in communication systems, instrument amplifiers, and various other electronic devices. A rotary switch can be used to control circuits, allowing the switch to be switched between different contacts.

A21403RNCB Rotary Switch

The A21403RNCB Rotary Switch is a versatile switch designed to meet a variety of applications. It has 4-positions and is suitable for switching between multiple electrical states. This switch offers reliable performance and long-term durability, making it a popular choice for high-end applications.

A21403RNCB Application Field and Working Principle

The A21403RNCB Rotary Switch is used in a variety of applications, including communication systems, instrument amplifiers, and various types of electronic devices.The switch is activated by rotating the shaft to different positions, allowing the user to control circuits between the contacts. The contact is composed of multiple insulated segments, which are fixed and configured in a specific way. This ensures that electrical current will not flow through the contacts until the correct contact is reached.When using the switch, the user inserts the shaft into the correct contact to activate the circuit. It is important to note that when the switch is switched to its off-state, the contacts are not connected, allowing disconnection of the device from the circuit.

Conclusion

The A21403RNCB Rotary Switch is an essential component of many types of electrical systems. Its reliable performance, long-term durability, and versatile design make it a popular choice for many applications. The switch is activated by rotating the shaft to different positions, allowing the user to control circuits between the contacts. This ensures a safe, secure connection, and eliminates potential for electrical current to flow through the contacts until the correct contact is reached.
