What type of switch is typically actuated by pressing a button?

A push button switch is designed specifically to be actuated by pressing a button. This type of switch can function either momentarily or as a maintained contact switch. When a button on a push button switch is pressed, it temporarily closes (or opens) the circuit, allowing current to flow (or stopping it). This mechanism is commonly used in applications where a simple, straightforward interaction is needed for control, such as in doorbells, electronic devices, or even machinery where a temporary action is required.

The design of the push button switch allows for quick and intuitive operation, making it ideal for scenarios requiring frequent on-and-off cycling. In contrast, other switch types have different mechanics and purposes: a knife switch is a type of electrical switch where a conductive blade moves into a slot, generally used in high-current applications; a selector switch allows the user to choose between multiple circuit paths; a toggle switch is flipped back and forth to open or close the circuit. Each of these has specific uses that do not involve pressing a button in the manner of a push button switch.
