Electromechanical toy with momentary actuator dual purpose cam mechanism preserving battery life
First Claim
1. A cam mechanism facilitating an automatic shut off mechanism for a toy, comprising:
- a motor;
an electrical power source;
an electrical switch in a circuit with the motor;
an internal actuator adjacent the electrical switch, the actuator is alternately in one of a first position where the motor is not powered and a second position in mechanical communication with the electrical switch for powering the motor;
a rotatable cam coupled with the motor, the rotatable cam including a peripheral cam surface having a recess where the internal actuator in the first position is captured in the recess, and where the internal actuator in the second position rides along the peripheral cam surface outside the recess and is in mechanical communication with the electrical switch powering the motor while the rotatable cam is operated by the motor;
a protrusion element at the cam; and
a manually operable actuator for applying a force upon the protrusion and advancing the cam forcing the internal actuator from the first position to the second position powering up the motor and rotating the cam, further rotation of the cam will move the internal actuator to the second position automatically shutting off the motor.

Abstract
A low cost cam mechanism facilitating an automatic shut off mechanism preserving battery life in a toy. A rotatable cam including a recess captures an internal actuator and completely shuts down a motor at a defined cam rotation to preserve the battery life in the toy. A resetting biasing lever coupled, to a manually operable actuator advances the cam and is then moved from engagement so as to completely shut down the motor at the defined cam rotation even if the manually operable actuator continues to be depressed. Further Thusly the internal actuator 18 facilitates limited activations of the motor for automatically shutting off a rotating cam mechanism to prevent repetitive continued operation. Further the internal actuator may provide powering up the motor and rotating the cam for “try me” operation for limited demonstrative operations of the toy while packaged or configured in a point of sale environment.
