7211J2ZQE3

Rocker switches are one of the most common switch types and are universally used in a variety of electrical and electronic applications. The 7211J2ZQE3 rocker switch is an example of a single-pole, double-throw (SPDT) switch. In an SPDT switch, there is one input that can be connected to two different outputs. The output of the switch depends on the direction of the switch lever: left or right, up or down, or some other combination of directions.

A typical 7211J2ZQE3 rocker switch has the following characteristics:

• Rated voltage and current: 12V/1A, 125V/3A.
• Mounting hole diameter: 19.3mm/12.5mm.
• Overall height: 14.25mm (without lever and rocker)
• Enclosed screw terminals: one per pole
• Adjustable actuator angle: 30° to 120°
• Lever: short or long
• Contacts material: silver-plated copper

The working principle of the 7211J2ZQE3 rocker switch is fairly simple. When the actuator (or switch lever) is moved in either direction (up, down, left, or right), the metal contacts inside the switch come together and bridging the two connections (input and output). If a voltage is then applied to the input terminal, it will also be passed through to the output terminal. When the actuator is released, the contacts separate and the connections are broken, shutting off the power supply and stopping current flow.

The particular application of the 7211J2ZQE3 rocker switch depends on the purpose for which it is being used. For example, it could be used in a device that requires a switch to turn power on and off. It could also be used in an automated system to actuate an event such as opening a door or activating a motor when the switch is moved in one direction or another. The possibilities are virtually endless, as rocker switches can be used in virtually any application where a switch is required.

The 7211J2ZQE3 rocker switch is a versatile, convenient and cost-effective option for a variety of electrical and electronic applications. It is compact, has robust construction, and can tolerate heavy loads. It is designed to be reliable, making it a great choice for any application that requires an on/off switch or an automated event to be actuated. It is also easy to install, making it an ideal choice for those with limited experience in electrical or installation work.
