Abstract

A remote control device having capacitive touch controls may be configured to enter a sleep state (or mode). For example, the remote control device may be configured to enter the sleep state upon expiration of an interval of time since a most recent button press. The remote control may be configured to awaken from the sleep state when one or more portions of a housing of the remote control are deflected, for example, when a user grasps the remote control to actuate one or more of the capacitive touch controls. For example, the remote control device may include a switch. The switch may include a carbon structure that may be configured to contact an open circuit pad on a circuit board to close the corresponding circuit when the housing is deflected and awaken the remote control device from the sleep state.
