SECTION 7 - BASIC ELECTRICAL INFORMATION & ELECTRICAL SCHEMATICS Current Measurement CHECKING SWITCHES Basic Check The following check determines if the switch is functioning properly, not the circuit in which the switch is placed. A switch is functioning properly when there is continuity between the correct terminals or contacts only when selected.
