Rocker Switches: U21J21CQE22 application field and working principle
U21J21CQE22 series of rocker switches are commonly used in many industries, such as machinery and electronic equipment, automobiles, and medical apparatus. The rocker switches are widely used in many applications thanks to their simple and durable construction, low profile, and cost-effectiveness. The U21J21CQE22 series has a low contact resistance and minimal current disruption, which makes them suitable for high current applications.

The U21J21CQE22 series is a single-pole double-throw (SPDT) rocker switch, and the contacts are preloaded with a return spring. The switch is operated by a rocker mechanism, which is actuated by a lever or plunger to open or close a circuit. The contacts are operated by a rotary arm, which swings from one contact to another as the switch is moved on its rocker axis. As the extreme positions are reached, the return spring presses the switch back to its default central position.

The U21J21CQE22 has a quick action, low contact resistance and long service life. It is also highly reliable against cycle per minute and can withstand high disc loads. The switch is UL rated and CSA listed. It is also IP67 rated, meaning it is dustproof and waterproof and can be used outdoors in harsh climates.

The U21J21CQE22 switch requires a minimum operating force of 9.89N and a minimum capacity of 6A at 250V AC. It is also designed to conform to IEC standard 60598-2-1 and can be used with UL and CSA approved components. The switch is also designed with an integrated dust cover, which helps protect the contacts from dirt and dust.

The U21J21CQE22 rocker switch is available in three sizes, with a variety of color options. The switches are suitable for use in a wide range of applications, including medical equipment, data and telecom equipment, test and measurement equipment, and control systems. The switch is also available with a range of accessories, such as end caps, dust guards, and indicators, making it suitable for a variety of applications.

In conclusion, the U21J21CQE22 series of rocker switches is a reliable and cost-effective choice for many applications. The switch is quick to actuate and offers low contact resistance, as well as a long service life. The switch is UL rated, CSA listed, and IP67 rated, giving it protection from dust and water. The range of sizes and color options along with a variety of accessories makes it ideal for a range of applications.
