Which switch opens and closes an electrical circuit by pushing the switch up and down with the thumb?

• A. Rotary Switch
• B. Push Button Switch
• C. Micro Switch
• D. Rocker Switch

Answer: (D)

The key idea is how the switch is actuated. A rocker switch changes state by a rocking motion of its actuator on a hinge. When you press on one edge with the thumb, the switch rocks to the opposite position, opening or closing the circuit. This up-and-down push with the thumb is the typical way a rocker switch is operated, unlike a push-button which is pressed in and usually returns, or a micro switch that is triggered by a small lever or button and a rotary switch which is turned. So the action described fits a rocker switch because its operation relies on a rocking motion to toggle between on and off.
