ABSTRACT:
The present invention is a combination of a motor having an unbalanced load thereon and an attitude switch (typically a mercury switch) in the activating circuit of the motor. The motor and the switch are securely attached to a substantially rigid framework in such a manner that, when in its stable horizontal position, the switch is in its off position and no motion of the motor, framework or switch occurs. When disturbed from the stable horizontal position, the switch closes the electrical activation circuit for the motor, resulting in vibration of the motor, switch and framework. This vibration causes the switch to be frequently, but not continuously, in the on position sustaining thereby the vibrational motion of the unit indefinitely until the framework (and the motor and switch securely attached thereto) is firmly held in the horizontal position for a brief period of time, typically a few seconds, causing the switch to come to rest once again in the stable off position. Such vibration mechanism may be used to impart amusing motion to a toy or other novelty item.
