Add a second start button to the basic circuit so Start Button 1 or Start Button 2 can be used to start a motor. Include a second stop button that is connected so that Stop Button 1 or Start Button 2 can be used to stop the motor.
Circuit Logic. Match each statement to the proper circuit. All circuits have been drawn with a light (L) to represent the load, whether it is a motor, bell, or any other kind of load. In addition, each switch is illustrated as a pushbutton whether it is a maintained switch, momentary switch, pushbutton, switch-on target, or any other type of switch.
