What type of switch has four connections and can control two circuits simultaneously? correct
answers DPST (Double Pole Single Throw)
Which material is a current limiter made of? correct answers Copper
What is the function of a switch in an electrical circuit? correct answers Control current flow by
altering resistance
What type of switch is commonly used as a position indicator switch for landing gear or flaps?
correct answers Proximity switch
What type of circuit protection device can be reset if tripped? correct answers Circuit Breaker
What can cause "chatter" in a relay? correct answers Defective coil circuit
What is the primary function of a relay in an aircraft's electrical system? correct answers Allow
remote control of circuits, especially where heavy currents are involved
What does "normally open (NO)" mean in switch terminology? correct answers Contacts are
open when the switch is not actuated
What is the primary purpose of circuit protectors in aircraft? correct answers Protect wiring from
overheating due to overloading or short circuiting
Which type of switch is primarily used as a limit switch for landing gear or flaps? correct

, Why is it critical to avoid using aluminum wire in high-vibration areas or where frequent
connections and disconnections occur? correct answers Aluminum wire is prone to breaking
under vibration
When selecting insulation materials for use in engine compartments, which characteristic is most
critical? correct answers Heat resistance
In wire marking, identification labels should be placed at what intervals along the length of the
wire? correct answers Every 12 to 15 inches
MIL-W-22759 wiring is recommended for post-1990 aircraft because it: correct answers Is
insulated with Teflon, providing better thermal resistance
