A momentary switch is one that only conducts while pressed.

• A. Momentary
• B. Maintained
• C. Latching
• D. Toggle

Answer: (A)

Momentary behavior means the switch makes contact only while you press it; as soon as you release, the circuit opens. That brief conduction is exactly what defines a momentary switch, used for signals that should occur only during actuation like push-to-start or doorbell presses. In contrast, a maintained or latching switch stays on after you press and release and only changes state when you act again to toggle it off. A toggle describes a type of action or form factor, not the sustained conduction behavior, and it can be either momentary or maintained depending on the design. So the statement fits a momentary switch because the current path exists solely during the pressed condition.
