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 is adapted for insertion into a specially configured opening in the mower housing to actuate and close the interlock switch. With the interlock switch closed, energization of the motor is controlled by a separate handle-mounted ON/OFF switch 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.
