ocr: It can be seen in the top drawing that the electricity comes in from the rignt,passes thru the "made" switch,along one of the "strappers" to the second switch but is prevented from Passing thru thus the light is off. In the bottom drawing all that is different is that the first switch is operated thus changing the in use "strapper" passing thru the unchanged switch continuing on to light the lamp. It can be seen that in the bottom drawing either of the switches could have been changed and the Lamp would have lit. Two WayLighting Hawk Industries
