Introduction to MLW3028-00-PB-1A Rocker Switches

Rocker switches are electrical switches which are operated by the user through a rocking action. The MLW3028-00-PB-1A rocker switch is a single-pole double-throw (SPDT) switch available in both surface mount and through-hole packages.

Application Fields

MLW3028-00-PB-1A rocker switches are commonly used in consumer electronic products; various industrial control and signalling devices; automotive, marine and avionics equipment; security systems; and the medical and telecommunications industries. In consumer electronics, they can be used to switch TV channels, adjust audio volume, and control motor speed. Industrial applications include motor control, process control, and machinery sequencing. The automotive, marine and avionics industries make use of the MLW3028-00-PB-1A for the control of lights, turn signals, and electrical systems.

Working Principle

MLW3028-00-PB-1A rocker switches are operated by a rocking action of a paddle or lever actuator. Signals are transferred as the contact changes state. When the paddle is moved up or down, it engages one of two contact sets, either opening or closing the circuit. The switch has low contact resistance, low noise, and excellent shock and vibration resistance. The contact is designed with a non-wetting wiper to ensure reliable operation in wet and dirty environments.The rocker switch operates by providing a connection between the two contact sets when the paddle is moved up or down. The paddle is connected to a cam mechanism that spring-loads the contact towards the switch’s center fulcrum. As the paddle is moved up or down, the contact is forced away from the center and engages either the normally open or the normally closed contact. When the paddle is released, the spring-loaded cam returns the contact to its original position.

Conclusion

The MLW3028-00-PB-1A rocker switch is a versatile and customizable SPDT switch widely used in the industrial, automotive, medical and telecom markets. With its low contact resistance, low noise operation, and excellent shock and vibration resistance, the MLW3028-00-PB-1A is an ideal choice for a variety of applications. The rocker switch’s working principle of using a spring-loaded cam and a paddle-driven contact allows it to easily be manipulated by the user while providing reliable switching.
