2. SWITCH CONNECTION
This figure illustrates a complex switch. The switch plates
indicated by solid lines move in the direction of the arrow
when operated. The continuity between terminals at each
position is as indicated in the table below.

CHECKING RELAYS
1. When current flows through the coil of a relay, its core is-
magnetized to attract the iron piece, closing (ON) the
contact at the tip of the iron piece. When the coil current is
turned off, the iron piece is made to return to its original
position by a spring, opening the contact (OFF).
2. By using a relay, a heavy current can be turned on and off by
a switch of small capacity. For example, in the circuit shown
here, when the switch is turned on (closed), current flows
to the coil of the relay.
Then, its contact is turned on (closed) and the lamp comes
on. The current flowing at this time to the switch is the relay
coil current only and is very small.
3. The relays may be classified into the normal open type and
the normal close type by their contact construction
NOTE
The deenergized state means that no current is flowing
through the coil and the energized state means that current
is flowing through the coil.
