Document Type and Number:
Japanese Patent JP2019036535
Kind Code:
A
Abstract:
To provide a keyboard with an illumination structure having a low profile and a simple structure.SOLUTION: In one aspect, an embodiment includes a key cap 110 having an illuminable symbol. A support structure having a pair of overmolded wings 122a, 122b may pivotally be coupled to the key cap. A switch housing may surround the support structure and connect each of the first and second wings. A tactile dome may be at least partially positioned within the switch housing and configured to bias the key cap upward. A sensing membrane may be positioned along an underside surface of the tactile dome and configured to trigger a switch event in response to a collapsing of the tactile dome caused by a depression of the key cap. A feature plate may be positioned below the sensing membrane. A light guide panel may define at least one light extraction feature that may be configured to propagate light toward the key cap and cause illumination of the illuminable symbol.SELECTED DRAWING: Figure 2A
