The electrical lighting wiring lighting-fixtures:
This is particularly true of electronic dimmers that do not work with a neutral connection (many need a tiny amount of power for their control circuitry) and for self-illuminated light switches. When using such a light switch, it would be normal for an open circuit to read “hot” all the time, but adding any sort of load should eliminate that effect. As an example, if you were to plug in a lamp then its power cord may read as “hot” when the two lamp and the wall switch are “off”, but switching on the switch to the lamp itself should cause it to cease reading “hot”

when the wall switch isn’t on; turning on the wall switch should then cause it to read “hot” while also making the lamp glow. If things behave as described here, particularly if the wall switch is an electronic dimmer or a self-illuminated model, that would suggest that everything is fine.
