Which of the following electrical parameters apply or are labeled to all kinds of switches?

The parameters that are universally applicable and labeled to all kinds of switches are rated current and rated voltage.

Rated current indicates the maximum amount of current that the switch can safely handle without overheating or sustaining damage. This specification is crucial as it ensures that the switch can operate within the electrical system without risk of failure. Rated voltage, on the other hand, refers to the maximum voltage that the switch can effectively interrupt or control. This parameter ensures the safe performance of the switch under varying voltage conditions.

Both rated current and rated voltage are essential for determining the appropriate use of a switch in an electrical circuit, making them universally applicable to all switch types. These ratings help in selecting the right switch for specific applications, ensuring both safety and functionality.

The other parameters listed, such as rated power, rated resistance, and combinations of these, are more specific and may not apply to every type of switch. For instance, rated power is relevant for devices that convert energy, while rated resistance pertains more to resistive components rather than switches themselves.
