Show THE Fig. SHINGLE-POL- TOGGLE SWITCH E A Fig. Since the first switch is at position (C), current flows directly through terminal (E) to terminal (F). then through handle (G) to turn on the light. Note than when either handle is placed- in the opposite position, the circuit is broken and the light goes out. Note also that if you swing either handle to the opposite position the current flow is made continuous and the light goes on again.

(Fig. I), and a three-wir- e feed cable from the first switch box to the second switch box. etc' The single-poltoggle switch has two brass terminal screws. One wire (usually the black) is cut and connected to the two brass terminals. The other wire (white) is continuous from the power source to the light or fixture. When connecting the wire to the terminal screw of a switch, always turn the loop on the end of the wire in the same direction as the screw threads. If the loop is turned in the opposite direction.

The red wire serves as a black wire from the switch to the light or outlet which is to be controlled. Fig. Fig. H F Th'f Switches B I.

You will note the white wire feed scontinuously from the power source to all fixtures. The black wire is looped on one terminal of the switch while the red wire attaches to the. other. The black wire then runs continuously through to the light or outlet which is not to be controlled while the red wire runs from the switch terminal to connect with the black wire on the controlled light or outlet. With this arrangement, the switch controls the first light or outlet while power continues uninterrupted to the second fixture. HOW A Sop R i" On;if lo' Im Li'ic Sw.t.
