Pushbutton Switches

Pushbutton switches are used in many applications such as everyday electronics and industrial control systems. They are most commonly used to control electrical circuits, switching between on and off states. Pushbutton switches are typically mechanical, but more and more electronic versions are being developed. Pushbutton switches come in a variety of shapes and sizes and have different voltage ratings.

IPR3FAD7/1 Application Field and Working Principle

IPR3FAD7/1 is a type of illuminated pushbutton switch from a leading manufacturer of pushbutton switches. The IPR3FAD7/1 is a low voltage (96V DC max) normally open momentary contact pushbutton switch, which is commonly used in applications such as traffic signals and machine control. The switch features a momentary action “button” that is flush-mounted to the face of the switch housing. The “button” must be pressed in order to activate the switch contacts.

The switch housing is constructed of die-cast aluminum, and the contact arms and spring clips are made of stainless steel, ensuring high performance and long operating life. The housing is designed to mount hole diameter of 1.25". The switch contacts are rated at 0.5A at 220V AC.

When a voltage is applied to the switch, the contacts will open and close depending on the position of the switch. The contacts close when the switch is in the off position, and the contacts open when the switch is in the on position. When the voltage is removed, the contacts will remain in their current state.

The IPR3FAD7/1 also includes a built-in LED that illuminates when the switch is in the on position. This helps to add a layer of safety, as it’s easy to distinguish when a switch is in the on or off position, even in poorly lit environments.

The IPR3FAD7/1 pushbutton switch is an ideal choice for applications where a momentary contact, illuminated switch is necessary. It has a rugged design and can operate in environments with high vibration and extreme temperatures (up to 105°C). It also requires minimal maintenance, making it a cost-effective, reliable power switch for a variety of industrial and commercial needs.
