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, light, or any other load. In addition, each switch is illustrated as a pushbutton whether it is a maintained switch, momentary contact switch, pushbutton, switch-on target, or any other type of switch.arrow_forward
