SAFETY SWITCH CONTACTS
WITH KEY INSTALLED.
Special wiring for the safety-interlock
switch to prevent tampering. The N.O
contact 23-24 short circuits the coil of
motor starter (M) with key removed. If the
N.C. contact 11-12 were jumpered, the
fuse would blow when the key is removed
from the switch and an attempt is made to
restart the circuit.
NOTE: Fuse to be 10 Amp slow acting or
16 Amp fast acting type.
