A rotary switch is an electrical switch that uses a rotating lever to make or break an electrical circuit. It is often used to control the various functions of a device that requires multiple on/off settings. The A20505RNCQK is a rotary switch designed to provide reliable performance in a wide range of applications. This article will discuss the A20505RNCQK\'s application field and working principle.The A20505RNCQK is a 20 amp switch with 5 poles and 5 positions. It is designed for use in industrial and commercial applications, such as HVAC, motors, power supply control systems and lighting. Its body and actuator are made of non-metallic materials, making it resistant to heat, oil and dust, and making it ideal for use in harsh environments.The A20505RNCQK has a wide range of switching options, from simple on/off switching to complex multi-position switching. It has a dual-gate mechanism that prevents the contact failure due to wear at one-pole positions by providing a second contact in the opposite position. It also has a long life expectancy of up to 20,000 switching cycles.The A20505RNCQK uses a simple working principle that involves the rotation of a lever to either make or break an electrical circuit. The lever is connected to a contact arm which has five arms, each one being connected to a pole or contact. When the lever is rotated, the arm moves in relation to the contacts and either makes or breaks the connection to the corresponding pole.The A20505RNCQK has a variety of applications and can be used in a wide range of industries, such as HVAC, motors, power supply control systems and lighting. It offers reliable performance in harsh environments and is designed to last for up to 20,000 switching cycles. It is easy to install and offers multiple switching options for the user\'s convenience.In conclusion, the A20505RNCQK is a reliable and durable rotary switch that is suitable for a variety of applications. It is easy to install and offers multiple switching options, making it an ideal choice for industrial and commercial use. Its long life expectancy and high resistance to heat, oil and dust make it an excellent choice in harsh environments.
