Embodiments are directed to a low profile key for a keyboard having an overmolded support structure. In one aspect, an embodiment includes a key cap having an illuminable symbol. A support structure having a pair of overmolded wings may pivotally couple 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.

An electronic watch may include a tactile switch and/or one or more sensors for detecting rotational and translational inputs. The watch may include a display configured to produce graphical outputs that may change in response to rotational inputs, translational inputs, and/or touch inputs received at the display. The watch include a crown positioned along an exterior of the watch enclosure and a shaft coupled to the crown and extending into the enclosure. The tactile switch and/or the one or more sensors may be used to detect rotational and/or translational inputs provided at the crown.

An open/closed indicating apparatus for a circuit breaker operating apparatus, comprising a button and an indicating element. The button is provided therein with a cavity. The indicating element is mounted within the cavity. The indicating element can rotate within the cavity. The button is provided thereon with an observation window. The indicating element can display different areas in the observation window while rotating. When a small number of gaps are provided between the indicating element and the housing, the impact on the angle of rotation of the indicating element is reduced, the indicating element can accurately indicate an open/closed state of a circuit breaker, and when a product is being fitted and assembled, a requirement on gap fitness is reduced for the assembly.
