Robot car kit Smart V3.0 - on/off switch does not work

Hi, after uploading the arduino software the car automatically starting moving around while the on/off switch was in the off position, how it this possible?? Seems the on/off switch does not work, it appears the car is always in the on position and moves around, any help apprecited. cheers


I played around with the switch, it was a connection problem, poorly built..but works now. thanks
