Zorluk: OrtaSwitches and Relays

In electrical and electronic control systems, electromechanical relays and multi-contact switches rely on specialized internal components and contact configurations to direct current and automate circuits. Match each switch or relay component to its primary mechanical or electrical operational function.

  • Common (COM) TerminalThe shared conductive connection point that routes incoming current to one of multiple selectable contact paths depending on switch or relay state
  • Relay ArmatureThe movable ferromagnetic component that physically transfers motion to open or close contacts when attracted by magnetic flux
  • Normally Closed (NC) ContactsThe contact pair that maintains a closed, continuous conductive path during the resting de-energized state and opens when actuated
  • Relay Solenoid CoilThe insulated wire winding wrapped around an iron core that produces an electromagnetic pulling force when control current flows through it

Cevap

Common (COM) Terminal matches the shared conductive connection point that routes current to selectable paths; Relay Armature matches the movable ferromagnetic component attracted by magnetic flux; Normally Closed (NC) Contacts match the contact pair that maintains a closed conductive path in the resting de-energized state and opens when actuated; Relay Solenoid Coil matches the insulated wire winding that produces an electromagnetic pulling force.
Each component corresponds directly to its mechanical or electrical role in relay operation: the Common terminal serves as the shared current pathway, the armature provides the physical motion via magnetic attraction, Normally Closed contacts provide resting continuity, and the solenoid coil generates the magnetic force from the control circuit.

Adım Adım Çözüm

1
Identify the function of the Common (COM) Terminal
Matched with the shared conductive connection point that routes current to one of multiple selectable contact paths.
In single-pole double-throw (SPDT) configurations and standard relays, the COM terminal is the central node connected internally to either the NO or NC contact.
2
Identify the function of the Relay Armature
Matched with the movable ferromagnetic component that physically transfers motion to open or close contacts.
The armature is the mechanical piece of iron that pivots when drawn toward the core by electromagnetic attraction.
3
Identify the function of the Normally Closed (NC) Contacts
Matched with the contact pair that maintains continuity during the resting de-energized state and opens upon actuation.
'Normally' designates the shelf or unpowered state, meaning NC contacts conduct electricity until an active force separates them.
4
Identify the function of the Relay Solenoid Coil
Matched with the insulated wire winding that produces an electromagnetic pulling force when control current flows through it.
The coil converts electrical input energy into a magnetic field via electromagnetic induction to drive the switching mechanism.
