Pushbutton switches are electrical switches used to control electric current flow in a circuit or system. The AV19402ZQE pushbutton switch is an example of such a switch, designed for a variety of low-frequency applications.

The AV19402ZQE pushbutton switch is a two-pole, single-throw, normally open pushbutton. It is a metal housing pushbutton switch, providing more rugged operation than plastic housing switches. It is configured with a black momentary contact, with a rated voltage of 12VDC and a 5A contact rating. The switch has a 1-inch threading for mounting to an electrical enclosure, and the switch is sealed to IP67 rating, making it suitable for use in water or dust environments.

The AV19402ZQE switch consists of two electrical contacts immersed in a dielectric fluid, with a moveable plunger-style button that interrupts the current flow when the button is pressed. The operating force required to move the plunger is approximately 0.32 N, and the electrical closure travel is approximately 0.7mm. The switch requires a maximum operating temperature of 65 degrees Celsius and a minimum operating temperature of -25 degrees Celsius, making it suitable for applications where environmental conditions may be extreme.

The working principle of the AV19402ZQE switch is simple. When the button is not pressed, the two electrical contacts are open, so no current can flow. When the button is pressed, the two contacts move toward each other, closing the electrical circuit and allowing current to flow. When the button is released, the contacts move away from each other, opening the circuit and breaking the current flow.

The AV19402ZQE pushbutton switch is designed for a variety of low-frequency applications, such as level adjusters and signal transmitters. It can also be used as a control switch for industrial machines, for applications such as pulsing, single-position selection control of alternating current applications, as well as limit switching, on-off control, and rotating machines. This switch is ideal for applications where waterproof and dust-proof protection is required, as well as applications where environmental conditions may be extreme.
