Pushbutton switches are devices specifically designed for manually controlling the operation of electrical circuits. Over the years, this class of switch have been continuously improved so that they can manage a range of electrical operations, from basic on/off switching and light dimming, to more complex tasks. One particularly useful and versatile pushbutton switch is the AV2220EA24T5Q04.

Application Field

The AV2220EA24T5Q04 is an industrial-grade pushbutton switch with 2 pole and 4-state switching capability. It is designed for applications that require manual operation, such as on/off switching of lighting, electromagnetic starters, emergency stops, and general industrial controllers. This switch is also very suitable for home automation systems, HVAC systems, and motor control applications, such as roller shutters. The AV2220EA24T5Q04 complies with UL, CE and TUV standards, making it suitable for a wide range of environments.

Working Principle

The AV2220EA24T5Q04 comprises a set of two normally-closed (NC) and two normally-open (NO) output contacts, which allow for 4-way operation. Two inputs are used to activate the device; these are controlled by external push buttons. When either of the push buttons is pressed, the corresponding output contact is engaged, while the other output contact remains disengaged, allowing control of a two-way circuit. When both push buttons are pressed simultaneously, both output contacts are engaged, which can be used to operate a four-way circuit.

The AV2220EA24T5Q04 features a manual snap-action mechanism that allows for quick, low-force operation. This mechanism also provides positive feedback, so the user knows that the switch has been engaged. The switch is highly durable, with an electrical endurance of more than 1 million operations, and a mechanical life greater than 5 million operations. This is complemented by a vibration resistance of up to 10G and an impressive insulation resistance of 1,000MΩ at 500VDC. The AV2220EA24T5Q04 is also resistant to dust, oil and water, making it suitable for a range of industrial and residential applications.

In conclusion, the AV2220EA24T5Q04 is a highly durable and reliable pushbutton switch, designed for a variety of applications. With its 2 pole and 4-state switching capability, it is suitable for a range of residential and industrial installations, making it a popular choice for electrical engineers and automation designers alike.
