Warning Signs Of A Defective Wall Switch
Light turns on when switch is off. It sounds like you have wired it so that when the switch is supposed be turning off the light it is actually turning on the switch and the wiring is such that it is shorting out the 115v from the. Then turn the breaker off that controls that light. 3 the reason the light remains on is that the light is permanently connected to another hot wire in the ceiling. Confirm that the light is off. After switching to leds or when replacing a faulty led lamp in some cases the led continues to glow weakly after turning the light switch offobserving this effect the first time could be very surprising the light switch is in the off position and the led lamp continues to glow. Led lights glow when switched off.
The remove the 2 screws holding the switch off. This problem can be felt by touch as the plastic piece is usually loose in the switch without any spring tension. In most of these cases the led just lights up very weakly but also this. The flip the switch over. In order for the light to work with the switch the ceiling light needs to be connected to the switched leg conductor coming off of the switch.

One mechanical failure easy enough to recognize is an internally broken toggle where the lever inside is unable or only occasionally able to activate the contactors. Turn the switch off then repeat the test. Turn the switch on then touch the tester leads to both of the brass terminals on the switch and verify that the tester led goes on. Is this down to induced voltages and a duff low. 120vac doesnt even bother me anymore. But best to shut off the breaker or fuse if you dont get along with ac current.
