Rotary Switches

Rotary switches are electromechanical devices that are used for switching electric current on and off. They are widely used in many applications, from transportation and industrial automation to consumer products. 50KM90-01B04N is one of the most common types of rotary switches available, and is commonly used in applications requiring high reliability and performance.

Application Field

The 50KM90-01B04N is a multi-pole, safety switch designed for switching electrical circuits in industrial, automotive, and consumer applications. This rotary switch is very popular due to its large contact force, low contact resistance, and wide current carrying capacity. It is widely used in a variety of applications, including automotive, industrial and consumer electronics.

Some of the most common applications of the 50KM90-01B04N include automotive power and communication wiring, HVAC systems, and consumer electronics. In automotive applications, the 5 pin or 6 pin versions of the 50KM90-01B04N are commonly used for switching power for sensors, lights, and fans. The 5 pin and 6 pin versions can also be used for switching automotive communications, such as CAN BUS and LIN communications.

In HVAC systems, the 50KM90-01B04N is commonly used for switching main power for air conditioners, heat pumps, and ventilation systems. It is often used for switching main power for humidifiers, dehumidifiers, and non-Standalone air-handler units. The 50KM90-01B04N is also highly effective in switching control power for single-phase, direct current motors.

In consumer electronics, the 50KM90-01B04N is used in a variety of products, such as DVD players and audio systems. It is commonly used in switching power and audio signals in car audio systems, home theater systems, and other entertainment systems. The 50KM90-01B04N is also used in some medical products, such as blood pressure and heart rate monitors.

Working Principle

The 50KM90-01B04N rotary switch is an inertial-mechanical device that uses a contact actuator to make and break electrical contacts. The contact actuator is a metal armature with a spring-fed roller that operates against a cam. The cam is mounted on the outer ring of the rotary switch and has multiple contact terminals. When the switch is operated, the armature is pushed outward and the roller moves against the cam, closing or opening the contacts.

When the switch is operated in the "on" position, it energizes the electrical contacts and current flows as normal. When the switch is operated in the "off" position, the metal armature is pushed back to its original position and the roller rolls down against the cam, breaking the contacts and interrupting current flow.

The 50KM90-01B04N is a robust and reliable switch due to its large contact force, low contact resistance, and wide current-carrying capacity. It is designed to be highly durable and reliable in a variety of applications.
