Pushbutton switches used in AV1911R312Q04 application field and working principle

Pushbutton switch has been an important component in the current electronic industry. Especially when power often needs to be switched on or off in large scale industry, it plays an even more important role in the process. AV1911R312Q04 is one of the different types used in the market today.

AV1911R312Q04 is a pushbutton switch that typical application field is industries such as airports, automotive, factory automation and many other indoor circumstances. Without further addressing the specific application, it is mainly connected with the control systems in that specified conditions. Operators can actuate the switch to switch an action on or off, with manual operation.

Furthermore, AV1911R312Q04 is an unlighted single pole double throw (SPDT) switch with solder terminals. As an example, when the switch is actuated and the first pole is pressed, the double-throw contact is thrown over, to activate the second pole. As a result, the switch will communicate with the control device and actuate the designated action.

In addition, this device needs to be reliable because of its usage in the specified industries. To improve its features, the AV1911R312Q04 offers a mechanical life of around 2 million cycles, a dielectric strength of 1 kV, a voltage of 125V AC at 4A, a contact resistance of 50m ohms, an insulation resistance of 100m ohms, and an environmental rating of 55/125℃.

Just like any other switch, the AV1911R312Q04 has its own dead zone and operating distance. The dead zone for this device is 1-4mm and total operating distance is 5,500mm. This range may be larger or smaller in some applications.

Also, this switch has a good operation force, which may vary depending on the application. Generally, the operating force is maintained at 100gf, allowing the user to press the switch with reasonable effort. In contrast, the released force should be lower than 25gf, meaning that the actuator should be able to return easily and quickly in its original inactive position, once it is deactivated.

Finally, most of the pushbutton switch should be sealed to prevent dust, moisture and other contaminants from getting in the device. To meet this requirement, manufacturers integrate the freely sliding actuator by utilizing a pressure fitting. This helps to keep the switch sealed and the actuator moves freely against the sealed contacts.

In a word, the AV1911R312Q04 is a reliable pushbutton switch for a wide range of industrial applications. It offers good flexibility with adjustable operating force, on/off action, excellent life and besides, embraces the sealed contacts to provide further protection from dust, moisture and other environmental factors.
