Switches are rated in maximum ___________ and ______________.

The correct answer identifies that switches are rated in maximum current and voltage. This is crucial for understanding how switches operate safely and effectively within an electrical system.

The current rating indicates the maximum amount of electrical current that the switch can handle without risking damage or failure. If a switch is subjected to a current higher than its rating, it can overheat, leading to potential failure or even fire hazards.

The voltage rating specifies the maximum voltage that the switch can endure while functioning properly. Exceeding this voltage can result in insulation breakdown or arcing across the contacts, which can similarly compromise the switch's integrity and performance.

Together, these ratings ensure that the switch is suitable for the intended application, helping to prevent operational issues and ensuring safety in electrical installations. Understanding these ratings is fundamental for anyone working with electrical components, ensuring that devices are matched appropriately to their operational requirements.
