U21-P4-H-Z-Q-E

Introduction to Toggle Switches

A toggle switch is a type of electrical switch that is actuated by a mechanical lever, handle, or rocking mechanism. Toggle switches are often used to control the on and off state of an electrical circuit. They are available in a wide variety of shapes, sizes, and colors, and with a wide range of electrical and mechanical specifications. This article will explain the application field and working principle of one particular type of toggle switch - the U21-P4-H-Z-Q-E.

How Toggle Switches Work

Toggle switches operate by opening or closing an electrical connection. When the switch is flipped from one position to the other, the contact points of the switch meet to form a complete circuit, allowing electricity to flow through the switch. Depending on the design of the switch, this may involve physically moving a set of metal contacts together, allowing an electric current to pass through the switch and complete the circuit.

U21-P4-H-Z-Q-E Application Field and Working Principle

The U21-P4-H-Z-Q-E is a small toggle switch suitable for many different applications. It is characterized by its electrical characteristics, which include a contact rating of 1/2A @125VAC and a UL, CSA and TUV approval rating. It is also very durable, and has a mechanical life of 10,000 cycles.

The U21-P4-H-Z-Q-E toggle switch has a two-pole single throw (DPST) actuation. This means that when the switch is in the “on” position, two terminals are connected and when the switch is in the “off” position, the two terminals are disconnected. As a result, this type of switch can control two devices simultaneously. The switch also has an illuminated LED, allowing the user to easily identify the on/off state of the switch.

One of the main advantages of the U21-P4-H-Z-Q-E is its robust design. The switch is constructed from a high-temperature resistance material, allowing it to withstand heavy use without degrading in performance. This makes it ideal for applications where a switch is required to operate in high temperature environments.

In addition, the device is also very easy to use. Its simple flip design makes it easy to operate, and the illuminated LED allows for easy identification of the state of the switch. This makes it ideal for applications where a simple switch is needed to power an electrical device.

Conclusion

In conclusion, the U21-P4-H-Z-Q-E toggle switch is a reliable and durable switch suitable for many applications. It is characterized by its two-pole single throw actuation design, high temperature resistance, and simple flip design, allowing it to easily and safely control two devices simultaneously. This makes it a great switch for applications where a reliable and robust switch is needed.
