### Answer:

The withstand voltage of a basic switch indicates the high voltage that does not break the insulation (1) between the same polarity terminals, (2) between current-carrying metal parts and grounds, and (3) between terminals and non-current-carrying metal parts.

### Explanation:

To measure withstand voltage, high voltage is applied between the following: two points of the same polarity terminals between COM-NO in the FP state and between COM-NC in the TTP state (in the case of the c-contact).
