Introduction: Rocker switches have been widely used in many electrical applications due to their reliable performance and low cost. They are designed to be manipulated with a rocking motion, typically with a toggle switch or lever. The 2641LHA21900L220V is a type of rocker switch, which will be discussed in this article.

General Overview: The 2641LHA21900L220V is a single-pole, double-throw (SPDT) rocker switch commonly used to route current in isolation between two circuits. It is rated for 10 Amps at 250V AC or 12 Amps at 250V DC. It has two inputs, one “Normally Open” (NO) and one “Normally Closed” (NC). When the lever is pushed one way, the Common (COM) connection is routed to the normally open contact, and when it is pushed the other way, the Common connection is routed to the normally closed contact.

Applications: The 2641LHA21900L220V is a versatile switch, with a range of applications. It is commonly used in motor control circuits, as it can be used to switch between stopped and running modes. Other applications include home appliances and industrial control panels, where it can be used as an indicator for switch positions, or as a manual switch for transitioning between alternate power sources. It may also be used in Access Control systems, as a means to enable and disable keypads and other electronics.

Working Principle: The 2641LHA21900L220V utilizes a single-pole, double-throw (SPDT) switching mechanism and is actuated by a toggling lever. The mechanical lever is connected to an actuator arm, which is linked to a roller cam. When the lever is pushed one way, the cam rotates, pushing the actuator arm towards the normally open contact, thus switching the current. When the lever is pushed in the other direction, the cam rotates again, pushing the actuator arm towards the normally closed contact and switching the current.

Conclusion: The 2641LHA21900L220V is a robust and affordable rocker switch commonly used in a variety of applications. Its basic operation involves a single-pole, double throw (SPDT) switching mechanism, which can be toggled by a lever to alternate between two circuits. Its versatile design makes it suitable for motor control, indicating switch positions, and transitioning between alternate power sources.
