Pushbutton switches, including 8551SZQE2 models, are primarily used to open and close an electrical circuit or to interrupt the flow of electricity in a specific section of a circuit. They are generally used to control the power supply of electronic devices, such as TVs, appliances, and computers. The 8551SZQE2 model is an ultra-miniature, illuminated pushbutton switch that is designed for applications that require a low-level electrical switch with an LED indication. It is perfect for applications such as retractable switches, LED indicators, and LED pushbuttons.

The 8551SZQE2 pushbutton switch consists of two parts, the switch and the LED indicator. The switch is the part with the contact pins, which open or close the electrical circuit when pressed, and the LED indicator is used to show if the switch is on or off. The switch is made of a dielectric material with an actuator (a small raised disc) and contacts (small metal pieces). The actuator is connected to a shaft, which moves when the switch is pressed. This in turn moves the contacts to either open or close the circuit. The LED indicator is typically mounted on the shaft and is illuminated when the switch is on.

The 8551SZQE2 pushbutton switch has an IP65 rating, which means that it is dust-proof and protected against water jets. The switch is designed to operate in environments with temperatures between -30C and +105C and can withstand up to one million operations. A wide range of installation options are available, including through-hole, surface-mount, and panel-mount for a more secure fit. It is also available with a range of light colours and intensities, such as blue, red, green, and white.

When it comes to the working principle of an 8551SZQE2 pushbutton switch, the switch is activated when pressed, which in turn moves the contact pins to either open or close the electrical circuit, depending on its configuration. The LED indicator is illuminated when the switch is on. The contact pins are normally open, meaning that the circuit is only closed when the switch is pressed. In a normally closed configuration, the contacts are already closed and the circuit is only opened when the switch is pressed.

The 8551SZQE2 switch is a great option for a number of different applications. It can be used in a variety of medical, automotive, and industrial settings, as well as for consumer electronics. The low profile and wide range of installation options make it well-suited for applications such as panel-mounted controls, gaming controllers, and push-button keypads. As for its industrial applications, the 8551SZQE2 can be used in low-level switch circuitry for instruments, control equipment, and production equipment.

In conclusion, the 8551SZQE2 pushbutton switch is an ultra-miniature, illuminated pushbutton switch that is designed for applications that require a low-level electrical switch with an LED indication. It is perfect for a wide range of applications and comes with a range of light colours and intensities to choose from. The switch is activated when pressed and the contact pins are either open or closed, depending on its configuration. The LED indicator is illuminated when the switch is pressed, indicating that the circuit is closed.
