Abstract
An electronic device is formed with a casing which houses a printed circuit board carrying a surface mounted switch. The casing has a hole through which a push-button portion of a switch actuator projects for operation by the thumb of a user. Because of design considerations the push-button portion has to be located approximately on the same plane as the printed circuit board. Accordingly the actuator has to be designed to convert inward motion of the push-button to motion in a direction perpendicular to the push-button motion so as to operate the switch. This is achieved by forming the actuator as a hook having a free end for engaging the switch and another end joined to the push-button and formed as a pivot.
