Abstract
Razor handles are provided for razors having a battery-powered functionality. Methods of manufacturing such handles are also provided. In one implementation, the handle comprises: a load comprising a motor coupled to a power source; a user-operable switch for controlling energy flow between the power source and the load; a control logic; an arming circuit to prevent the user-operable switch from causing drainage of the power source; and a locking circuit that receives a switch signal from the user-operable switch and an arming signal from the arming circuit, wherein the locking circuit outputs a motor control signal to the control logic in response to the states of the switch signal and the arming signal, wherein the arming circuit comprises a timer for changing the state following lapse of a time interval and an arming switch having a first state and a second state.
