Abstract
A switch module for an electronic device detects translational inputs and defines at least portion of a conductive path from an input surface of the electronic device to a processing unit of the electronic device. The switch module may be a component of a crown assembly for detecting rotational inputs, translational inputs, touch inputs and/or biological signals such as electrocardiogram (ECG) signals. The switch module may include a conductive dome and a friction guard that is positioned between the conductive dome and the actuation member of the crown assembly. The conductive dome and/or the friction guard may define at least a portion of the conductive path from the input surface to the processing unit.
Claims20
An electronic watch comprising:
- an enclosure defining an interior volume and an opening into the interior volume;
- a processing unit positioned within the interior volume;
- a display operably coupled to the processing unit and configured to provide a graphical output;
- and
- a crown assembly positioned at least partially within the interior volume, the crown assembly comprising:
- an actuation member extending through the opening and defining an input surface for sensing an input signal along an exterior of the electronic watch;
- a rotation sensor positioned within the interior volume and configured to detect a rotational input at the crown assembly;
- and
- a switch module positioned within the interior volume and comprising:
- a switch housing defining a recess;
- a persistent electrical contact positioned in the recess and conductively coupled to the processing unit;
- a switch electrical contact positioned in the recess and conductively coupled to the processing unit;
- and
- a conductive dome positioned at least partially in the recess and conductively coupled to the actuation member;
- the conductive dome configured to transition from an uncollapsed configuration to a collapsed configuration in response to a translational input at the actuation member;
- wherein:
- in the uncollapsed configuration and the collapsed configuration, the conductive dome contacts the persistent electrical contact to at least partially define a conductive path between the input surface and the processing unit;
- in the collapsed configuration, the conductive dome contacts the switch electrical contact to register the translational input;
- and
- the graphical output is responsive to the input signal, the rotational input, and the translational input.
A switch module for a crown assembly for an electronic watch, comprising:
- a switch housing comprising:
- a base defining a recess;
- and
- a bracket for coupling the switch module to a device enclosure;
- a conductive dome positioned at least partially in the recess and defining a first portion of a conductive path between an actuation member and a processing unit, the conductive dome configured to transition from an uncollapsed configuration to a collapsed configuration in response to a translational input at the actuation member;
- a friction guard contacting the conductive dome and configured to be positioned between the conductive dome and the actuation member, the friction guard defining a second portion of the conductive path;
- a persistent electrical contact positioned in the recess and contacting the conductive dome, the persistent electrical contact defining a third portion of the conductive path;
- a first conductive member at least partially encapsulated within the base and defining a fourth portion of the conductive path;
- a switch electrical contact positioned in the recess and configured to contact the conductive dome in the collapsed configuration to register the translational input;
- a second conductive member at least partially encapsulated within the base and configured to conductively couple the switch electrical contact to the processing unit.
An electronic watch comprising:
- an enclosure defining an interior volume and an opening into the interior volume;
- a processing unit positioned within the interior volume;
