Aluminum oxide control mechanism

摘要

A control mechanism comprises a housing defining an interior and an exterior, an aperture formed in the housing and extending from the interior to the exterior thereof, an actuator on the interior of the housing, proximate the control aperture, and a control member positionable within the aperture to operate the actuator. The control member comprises a first surface exposed to the exterior of the housing, a second surface proximate the actuator within the housing, and a body portion extending therebetween, the body portion being formed of a substantially single crystal aluminum oxide material. A bias member is configured to bias the body portion of the control member toward an inner surface of the housing, such that the control member is retained within the aperture in operation of the actuator.

1. A control mechanism comprising:
a control aperture defined in a device housing, the control aperture extending through the device housing from an interior to an exterior thereof; a control actuator on the interior of the device housing, proximate the control aperture; a control member positionable within the control aperture to operate the control actuator, the control member formed from a substantially single crystal aluminum oxide material and comprising:
a first surface exposed to the exterior of the device housing;a second surface proximate the control actuator within the device housing; anda body portion extending therebetween;and a bias member configured to bias the body portion of the control member against the device housing, such that the control member is retained within the control aperture in operation of the control actuator; wherein the first and second surfaces of the control member oriented along parallel crystal planes the substantially single crystal aluminum oxide material.
