Across
- 3. A relay's contact can be either normally open or normally this. (2 wrds.)
- 4. Device that allows low-power circuits to control high-power circuits.
- 7. A contactor or relay uses this to control electrical power.
- 10. This part of a contactor helps it physically move contacts. (2 wrds.)
- 11. A contactor coil is typically powered by this type of current.
- 12. Electrical device used to control high-current circuits.
- 13. A relay's electrical symbol usually indicates this type of coil.
Down
- 1. Type of contact that closes when the coil is energized. (2 wrds.)
- 2. Used to protect circuits from electrical overloads.
- 5. The ability to open or close a circuit is known as this.
- 6. Component that opens or closes electrical contacts in a circuit.
- 8. A type of relay that switches larger currents.
- 9. The energy used to operate the contactor or relay's mechanism.
