<p>An electro-mechanical interlock and module system for an electrically powered device such as a cordless, electric lawn mower that includes a normally open interlock switch for controlling the enabling of the power circuit for the lawn mower. A key member (20) is adapted for insertion into a specially configured opening (56) in the mower housing (14) to actuate and close the interlock switch (32). With the interlock switch (32) closed, energization of the motor is controlled by a separate handle-mounted ON/OFF switch (18) in a conventional manner. In addition, a modular assembly technique is disclosed which facilitates ease of manufacturing while assuring proper alignment between the various components of the interlock system. <IMAGE></p> |
