ABSTRACT:
A toy house has a lamp for illuminating an interior of the toy house and a switch which is magnetically actuated by placing a play piece having magnet disposed in its bottom surface area in proximity to an end of a lever which carries magnetically attractable material. When the end of the lever moves towards the play piece due to magnetic attraction, the opposite end of the lever causes two contacts to come into electrical contact with each other.
