This application uses light bulbs to illustrate the operation of the switch contacts during actuation. In its normal state, the switch actuator is not being pushed and the light connected to Terminal B is illuminated while the light connected to Terminal A is not illuminated. When the actuator is depressed, the light connected to Terminal B will turn “off” and the light connected to Terminal A will illuminate. Once the switch actuator is released, the contacts will return to their normal state again.
