Toggle Switches

The U21P4CWZQE is a type of toggle switch which has a wide range of applications. Toggle switches are mainly used in electronic control systems to switch circuits on and off, control the flow of electricity, and act as a signal or indicator.

Application Field

Toggle switches can be used in a variety of applications such as automotive, lighting, commercial and industrial, telecom and networking, computer and peripheral, vivarium and aquarium, kiosks and displays, marine, and HVAC. For example, a toggle switch might be used to control the headlights of a car or to control the speed of a fan.

The U21P4CWZQE is particularly well-suited for applications requiring very small switches, as it has an ultra thin profile of just 4mm. It is also very reliable, with a mechanical life of 500,000 cycles, and features a positive tactile feel when switching.

Working Principle

Toggle switches work by interrupting the flow of current. When the toggle switch is off, the circuit is open, and current cannot flow. When the toggle switch is turned on, the circuit is closed, allowing current to flow. This process is repeated each time the toggle switch is switched.

The U21P4CWZQE has two pins on each side, which are connected when the switch is closed. This type of toggle switch uses a copper and brass alloy as contacts instead of the traditional metal contacts. This ensures a greater resistance against corrosion and an increased mechanical life.

The U21P4CWZQE also has a waterproof boot, which provides protection against dust and water, making it ideal for applications in marine and outdoor environments. Additionally, the double-pole construction prevents contact acceleration, giving the U21P4CWZQE superior protection against electrical or mechanical failure.

Conclusion

The U21P4CWZQE is a versatile toggle switch with a wide range of applications. Its ultra thin profile and waterproof design make it suitable for use in outdoor and marine environments. It is also very reliable, with a mechanical life of 500,000 cycles.
