Abstract

Improved timer-switch for dollhouse, essentially characterized in that it is constituted by an advantageously tubular body, which, through a central partition, defines two chambers, of which one houses a counterweight displaceable against the action of an expansion spring, interposed between the septum and the counterweight, meanwhile, the second chamber contains a pneumatic bellows with valve regulating device of the entrance-exit of the air, and whose bellows impels to a contiguous piston provided respectively with an axial shaft that crosses the orifice of the septum separator between chambers, and of a contactor metal body, for this purpose counting the separating partition between cameras with the corresponding contacts of the voice device of the wrist, such as that of crying, so that, during the sonorous emission of the latter, through movement of the same, the counterweight hits alternately on the plunger rod, p rooting the descent of the latter and the opening of the circuit of the voice, in the course of whose descent, the piston itself has been compressing the bellows, until the aforementioned knocking of the counterweight ceases, at which time, actuates in opening the valve itself bellows and originates the gradual recovery of the same until the metal body reaches the plunger the contacts of the partition, producing then the closure of the circuit and the start-up of the voice mechanism.
