Laser remained 'on' even if switch is in 'off' position

Hi,

I used the Laser cutter yesterday and noticed that the laser remained on even when the switch was in the off position.
Secondly, the red light (of the laser switch) that glows when the switch is ‘on’ remained on even when the switch was in the off position and at other times, the light was ‘on’ in the off position.
FYI.
