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 po-
sition is as indicated in the table below.
NOTE
M denotes continuity between terminals.
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 light 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 kurrent is flowing
through the coil and the energized state means that current is
flowing through the coil.

NOTES
1. CRANKING RATING is the current a battery can deliver for 30 seconds and maintain a terminal voltage of 7.2 or
greater at a specified temperature.
2. RESERVE CAPACITY RATING is the amount of time a battery can deliver 25 A and maintain a minimum terminal
voltage of 10.5 at 26.7”C (80°F).
