U21J3ZQE3 rocker switches are known for their widespread use in applications where minimal size, extended life and quiet operation are key design requirements.

These switches have a variety of applications in automobiles,appliances, aerospace and telecommunication and medical technologies. Some of the most typical applications are in audio-visual equipment, white goods and computer peripherals.

Rocker switches can be AC and DC rated and therefore can be used in high current applications. The contact assembly is typically hermetically sealed with a molded epoxy insulator for protection from the environment. The sealed contact assembly has a long life and is dirt, dust and moisture resistant.

Operating Principle:

The U21J3ZQE3 switch is typically operated via a guide wire which connects from the rear of the switch to an adjacent structure or surface. This guide wire is then connected to a contact or lever arm located on the rear side of the switch, thereby providing a switch action similar to that of a rotary or toggle switch but with a smooth, linear action.

When the contact is depressed, it will move slightly, activating the switch\'s internal contact assembly and completing the electrical connection, which then allows a current to flow through the switch. Depending on the type of switch, the design, and the current rating of the switch, either a normally open or a normally closed contact will be eneterd when the switch is activated.

The U21J3ZQE3 switch is designed to provide a long life and to keep the contact smooth, quiet and reliable. It is available in a variety of configurations, with multiple mounting options. Some of the most typical configurations are different mounting depths, switch types, and body shape. Additionally, some configurations offer a double or triple pole configuration, allowing for multiple circuits to be controlled simultaneously by a single switch.

The U21J3ZQE3 is great for applications with space and size limitations. It utilizes the same operating principles as other switches but with the space-saving features that make it ideal for space-constrained applications. It is also a great option for applications where a reliable and quiet operation is required. The design and construction of the switch ensures that a long life is possible and that the switch will remain activatable over time.
