ABSTRACT:
Methods and apparatus for controlling energization of an appliance motor are described. The apparatus, in one embodiment, may include a condition responsive switch secured within an appliance motor casing to control the energization of the appliance motor windings. In one mode of operation, the condition responsive switch substantially prevents energization of the motor windings if at least one attachment has not been substantially properly secured to the appliance, and the switch substantially properly secured to the appliance.
