Pushbutton Switches

Pushbutton switches are devices commonly used in electrical systems and provide an easy way to manually control the flow of electricity. The 520.03-YEL pushbutton switch is an example of one such device. This switch is a single pole, double throw (SPDT) switch, meaning it can be used to control two different circuits, as it contains three terminals: one common, one normally open, and one normally closed.

The 520.03-YEL pushbutton switch is a great choice for applications requiring a momentary action switch, such as games and toys. It is a small switch, with a height of only 6.35mm, making it unobtrusive when installed. The switch is able to withstand up to 20A at 125VAC/250VDC, making it suitable for high power applications. Additionally, the switch is UL Recognized and CSA Certified.

Application Field

The 520.03-YEL switch is a versatile device that can be used for a wide range of applications. It is commonly used for controlling lights and other devices in home automation systems, as well as for controlling motors and other devices in industrial applications. Additionally, the switch can be used to control power in audio equipment, such as amplifiers and loudspeakers.

Working Principle

The 520.03-YEL is a momentary action switch. That means that when the switch is pressed, it forms a circuit and allows electricity to flow. When the switch is released, the contact opens and the circuit is broken, stopping the flow of electricity. This makes the switch ideal for applications where a temporary or short burst of electricity is desired, such as a loud burst of sound from an amplifier.

The 520.03-YEL is also available with a latching action, meaning that the switch stays in the “on” position until manually switched off. This feature is ideal for applications where a constant flow of electricity is desired, such as a lamp that needs to remain lit. The latching action version also requires two separate pushbuttons (one to switch on and one to switch off) to provide proper functionality.

Conclusion

The 520.03-YEL pushbutton switch is a versatile device that can be used for a wide range of applications. It is a small, yet powerful switch that is able to withstand high currents and is UL Recognized and CSA Certified. The switch can be used in momentary or latching configurations, making it suitable for applications requiring a short burst of electricity or a constant flow of electricity.
