Pushbutton Switches

Pushbutton switches are electronic switches that are activated by pressing a button or actuator. They are commonly used in a variety of applications, such as industrial control systems, consumer electronics, and medical devices.

Pushbutton switches typically consist of a housing, a button or actuator, and a set of electrical contacts. When the button or actuator is pressed, it completes a circuit between the contacts, allowing electrical current to flow through the switch.

Pushbutton switches come in different configurations, including momentary, latching, and toggle switches. Momentary switches are activated only while the button or actuator is pressed, while latching switches remain in the on or off position until manually reset. Toggle switches have a lever or toggle that can be flipped to turn the switch on or off.

Pushbutton switches offer several advantages over other types of switches. They provide a simple and easy-to-use means of controlling circuits, and they offer tactile feedback that can help to ensure reliable operation. They are also highly durable and can withstand frequent use and harsh environments.
