Pushbutton switches are widely used in various fields such as industrial, commercial and residential, from automation to home appliances. 3PB7 pushbutton switches are no exception and are widely used in a variety of applications. Let us take a closer look at the application field and working principle of 3PB7 pushbutton switches.

3PB7 pushbutton switches are mainly used in industrial control, power system, switchgear, and metering devices. They are designed to control and protect electric circuits, as well as be used in various automated device operations. They are also used for emergency equipment control and switchgear maintenance. With its modular design, the 3PB7 switch provides better safety and convenience than general switches.

3PB7 switch is equipped with three buttons: ON, OFF and SELECT. When the ON button is pressed, it activates the switch and power is supplied to the circuit. Meanwhile, pressing the OFF button will cut off the power supply and deactivate the switch. The SELECT button can be used to select the operating mode of the switch. Depending on the model, the SELECT button can be used to adjust the speed, pressure or other variables while the switch is active.

The 3PB7 switch uses a direct opening mechanism, which limits the damage caused by a power failure or short circuit. This ensures that the switch can be switched on and off quickly and safely every time. The comb-shaped opening also reduces contact spark, which can be helpful in reducing the chances of a fire or other explosion.

The 3PB7 switch also has a built-in self-test system, which detects the voltage and current flow on the circuit. Whenever an abnormal condition is detected, it will trigger an alarm and power can be cut off before any damage occurs. This is especially useful in industry applications, as it eliminates the need for regular personnel inspections.

In conclusion, 3PB7 pushbutton switches can be used in a wide variety of applications. Their modular design, secure opening mechanism and built-in self-test system makes them a popular choice for industrial automation, switchgear, and other applications. As a result, the 3PB7 switch is gaining popularity among professionals and hobbyists alike.
