Which switch makes contact when a button is pressed and breaks contact on the release?

• A. Normally Open
• B. Push Button Switch
• C. Relays
• D. Micro Switch

Answer: (B)

A switch that closes the circuit only while you are pressing the button is a momentary, button-actuated device—the Push Button Switch. When you press it, the contacts make and current flows; when you release, the contacts open and the circuit breaks. The term normally open describes the default state of the contacts (open until pressed), but the question is about the type of switch based on how you operate it, which points to a push button switch. Relays and micro switches are different devices or configurations and don’t specifically capture the act of pressing a button to make contact.
