An electrical device such as, for example, an electrical switch is disclosed. The switch being arranged and configured to prevent ingress or intrusion of water, dust, or the like from the external environment thus making the switch particularly suitable for use outdoors or indoors where water and dust are expected. In one embodiment, the switch includes a base or housing, an internal actuator positioned within an internal cavity of the base, an external actuator accessible by a user, a barrier layer positioned between the internal actuator and the external actuator, the barrier layer arranged and configured to seal the internal cavity and the internal actuator, and a magnetic coupling arranged and configured to transfer movement of the external actuator to the internal actuator through the barrier layer.

A switch device includes an operating knob on which a tilting operation is performed, a detected portion that tilts with the tilting operation of the operating knob, a detection portion that detects movement of the detected portion, and a substrate on which the detection portion is arranged. The detection portion is aligned in an in-plane direction of the substrate and performs a switching operation upon detection of movement of the detected portion in the in-plane direction.

A switch device includes two fixed contacts and a movable contact of which position is changed when an operation unit is operated to selectively contact the fixed contacts. The switch device also includes a snap action mechanism that switches a contact state of the movable contact with the fixed contacts by deforming a spring portion in accordance with an operation amount of the operation unit. The switch device also includes a control unit that determines an operation state of the operation unit based on a detection signal received from the fixed contacts and the movable contact.

An internal support bracket for a power switch includes a bottom support and a top cover. The top cover is secured to the bottom support. The combined bottom support and top cover define an aperture for securing the power switch. The bottom support includes a bottom surface with a ridge protruding therefrom. A method of securing a power switch to the interior of a computer chassis includes connecting a base support including a channel to an interior wall of the computer chassis. A power switch is positioned between a top cover and a separate bottom support. The separate bottom support includes a ridge protruding from a bottom surface. The top cover is secured to the separate bottom support. The ridge of the separate bottom support is slid into the channel such that the internal support bracket including the power switch is secured in a locked position.

A key structure includes a bottom plate, at least one keycap, and a thin-film circuit board. The bottom plate has at least one elastic protruding portion. The keycap is liftably connected to the bottom plate and has a press portion and at least one trigger portion. The press portion is located at a central region of the keycap and faces the elastic protruding portion, and the trigger portion is located at a peripheral region of the keycap. When the key is lowered from a first position to a second position relatively to the bottom plate, the press portion downwardly presses the elastic protruding portion, and the press portion triggers an electrical trigger point of the thin-film circuit board. The keycap is adapted to be restored from the second position to the first position through an elastic force of the elastic protruding portion.

An electrical switch device including a switch housing having first and second compartments separated by a partition; an electrical switch assembly disposed in the second compartment; a control knob configured for seating adjacent to the first compartment, and having a user engagement portion and a plunger configured to extend from user engagement portion from the first compartment in to the second compartment via an opening in the partition separating the first and second compartments when the control knob is seated, and said plunger being configured for movable interaction with the electrical switch assembly; and a sealing member including a base portion configured for securing of the sealing member to the housing, and, a tubular portion extending from the base portion and configured to surround the plunger so as to alleviate ingress of liquid from the first compartment in to the second compartment via the opening in the partition.
