Rocker switches are operating devices composed of a type of switch mechanism that operates by being pressed up and down or side to side. The part number 7211J16Z3QE22 belongs to a durable 30A double pole double throw rocker switch. It features a two-gang housing and four terminals, two of which are quick connect, making it an ideal choice for applications such as power boats and off-roading vehicles.

The working principle behind this rocker switch is simply moving the handle up or down to make or break the electrical circuit. Depending on the design, a single-pole single-throw (SPST) rocker switch will open or close one circuit and a double-pole single-throw (DPST) will open or close two separate circuits. There are other versions, such as the single-pole double-throw (SPDT) and the double-pole double-throw (DPDT), which refer to the number of electrical circuits and poles in the switch, not just the number of contacts and connections.

It is useful in applications that require switching between Polarised and Non-Polarised circuits, as the four terminals make it a capable Pan-Connect solution. It also usually boasts a high-current rating, and can be used for lighting, pumps, fans, warning systems and other electrical devices. Additionally, this back-lit switch has a very low profile and requires no mounting hardware.

The 7211J16Z3QE22 switch offers convenience and reliability with its double-pole construction, which allows a single switch to control two separate circuits. With its corrosion-resistant silver contacts, this rocker switch will ensure a reliable electrical connection can be made and maintained for a long time. Furthermore, the lightweight and shock-resistant construction provides user confidence and peace of mind in even harsh environments.

Rocker switches are widely used in many different applications including automotive, marine, and industrial projects. Depending on the application, there are a range of rocker switches available in a wide variety of styles, colours, configurations, and sizes. With the innovative design of the 7211J16Z3QE22, it is the perfect example of the diversity of rocker switches and the various applications that this type of switch can be used for.
