Rotary switches, sometimes called turning or selector switches, are a specialized type of switch that are used to control a wide range of electrical and electronic circuits. The A20642RSCQE is a specialized type of rotary switch that is designed to switch between two different circuits. It is particularly well-suited for applications in which multiple circuits must be switched rapidly, while maintaining a low level of contact resistance.

The A20642RSCQE is a type of rotary switch that is designed to provide low-resistance switching between two different circuits. This is accomplished by using two sets of contacts, each set containing two contacts. When the switch is actuated, the contacts bridge between the two circuits, allowing current flow through the selected circuit. The contacts of this rotary switch are made from resilient materials that are resistant to wear, allowing the switch to be used in high-frequency switching applications.

The A20642RSCQE rotary switch can be used for a variety of applications, including in industrial control, automotive, and communication systems. In industrial control applications, the switch can be used to rapidly switch between two power sources or to control multiple circuits. In automotive applications, the switch can be used to select between different operating modes, such as cruise control and power-on/off.

In communication systems, the A20642RSCQE switch can be used to rapidly switch between different antenna elements, providing improved signal strength and reception. The switch is also commonly used in radio frequency (RF) applications, where it can be used to switch between different RF circuits.

The working principle of the A20642RSCQE switch is simple. When the handle is turned, it actuates a small cam that pushes against the contacts, bridging them together and connecting the two circuits. The contacts are designed to be low-resistance and resilient to wear, ensuring a reliable connection. The switch is also designed to be resistant to vibration and shock, making it suitable for use in industrial and automotive environments.

The A20642RSCQE rotary switch is a versatile and reliable switch that can be used in a wide variety of applications. Its low-resistance contacts and robust construction make it well-suited for high-frequency switching applications, while its resilience to vibration and shock make it ideal for use in industrial and automotive environments. Its simple working principle and low-resistance contact design make it particularly well-suited for switching between two different circuits.
