Rocker switches are well-known for their versatility and wide range of applications. WB242D1921 is one of the most popular rocker switches used in industrial and automotive applications. This rocker switch has a built-in normally closed (NC) contact, which allows for flexibility in system design. With a single switch, it is possible to turn one component on and off, or to control multiple components. Wall mountable and panel mountable versions are available, which makes the switch suitable for many types of installations.

The WB242D1921 has a current rating of 10A at 250VAC, allowing it to handle some of the higher current loads. This makes it suitable for larger motor and lighting applications, such as commercial refrigeration and industrial machinery. Operationally, the switch has a double break contact system with a single operating button. This allows it to be used to control a single component or multiple components. An LED indicator light is integrated on the switch, allowing it to be used in tandem with lighting systems. The LED light can act as a warning or indicate when the system is in use.

In terms of construction, the WB242D1921 is built with a rugged metal housing and metal contacts for added durability. The switch has an IP44 dust and fingerprint-proof rating, making it suitable for indoor and outdoor uses. The metal housing contains PCB terminals that are designed to be soldered directly onto a PCB board. The metal contacts are gold-plated and designed to resist oxidation and corrosion. This makes the switch a great choice for applications that require a long-term, reliable connection.

The operation of the WB242D1921 is designed to be very simple. The switch is activated by pushing the button down. This will cause the integrated NC contact to open, allowing current to flow through the circuit. When the button is released, the NC contact will close, stopping the current flow. This allows the switch to be used to control one component or multiple components at the same time.

Overall, the WB242D1921 is a versatile and reliable rocker switch that is suited for a wide range of applications. With a high current rating and an IP44 dust and fingerprint-proof rating, the switch can be used both indoors and outdoors. The integrated NC contact and LED indicator light make it suitable for controlling multiple components at once. The switch is easy to install and maintain, making it ideal for a range of different applications.
