b) Normally Closed Switch (NC)
To test a normally closed switch connect the ohmmeter between the switch
terminals.
• The meter should indicate a closed circuit (zero resistance «0»).
• Activate the switch. The Ohmmeter should indicate an open circuit (zero
resistance «°°»).
This indicates the switch is operating properly. Variation from test results de-
scribed indicates a defective switch.
The diagrams show the connections of the electrical components in different situations.
NOTE
- The continuous line indicates the electrical continuity of the circuit. All switches are shown
from the rear.
