A rotating switch contact apparatus has an apparatus housing; a contact housing; a housing bearing provided in the contact apparatus housing, the housing being rotatably mounted in the bearing; and a contact bridge mounted in the housing, rotating with the latter and having, at each end, a stationary mating contact receptacle, receptacles protruding from housing openings so the receptacles engage stationary mating contacts during contact housing rotation and may produce electrical contact between stationary mating contacts via the contact bridge. At least one spring terminal is arranged between the housing and bridge, which is resiliently mounted in the housing approximately perpendicular to the apparatus rotational plane. The contact housing is approximately cylindrical and at least partially has, on its lateral surface, a gearwheel section, and has an opening through which the gearwheel section projects, so the housing is rotationally movable for contact opening or closing between stationary mating contacts and receptacles via a gearwheel engaging in the gearwheel section.

A multi-directional operation switch that can be miniaturized is provided. The multi-directional operation switch includes an operation rod that is rotatable about an operation rod axis, and is also tiltable. The operation rod has an inner end portion inserted in a hole in a circuit substrate, and a slider, which operates in conjunction with an operation of the operation rod, is provided on the inner end portion. The slider has a movable contact. The circuit substrate has a plurality of fixed contacts that are brought into contact with, and are electrically connected to, the movable contact when the slider rotates or slides.

A control device with limit switches is provided. The device has a container housing an electric circuit provided with one or more limit switches, and a driving assembly configured to control operation of a valve or an actuator through the limit switches of the electric circuit. The driving assembly has a shaft configured to be rotatably coupled to a valve or an actuator and one or more cams keyed on the shaft and is configured for driving the limit switches of the electric circuit. The shaft has a gripping surface and each cam has a radial clamping mechanism whose gripping members are arranged in correspondence of a through hole configured to allow to fit the cam onto the shaft.

Electronic devices are provided that have components. A housing protrusion may be interposed between a display cover layer and display components. A button may have a button member. A support structure for a dome switch in the button may have a screw hole. A housing may have screw holes through which a screw passes. The screw may also pass through the screw hole of the support structure to hold the switch structure near the button member. A clip may have a spring. A metal plate may prevent the clip from becoming worn by the spring. A display may be mounted on a ledge in a device housing. The ledge may have gaps with supports and removed corners.

This application relates to various button related embodiments for use with a portable electronic device. In some embodiments, a snap clip can be integrated with a button bracket to save space where two separate brackets would take up too much space in the portable electronic device. In other embodiments, a tactile switch can be waterproofed by welding a polymeric layer atop a tactile switch assembly. In this way water can be prevented from contacting moisture sensitive components of the tactile switch assembly. The weld joining the polymeric layer to the tactile switch can include at least one gap to trapped gas surrounding the tactile switch assembly to enter and exit during heat excursions caused by various operating and/or assembly operations.

A disconnector for photovoltaic applications having at least two modular contact boxes, each contact box having a box-like body coupled to a contiguous box-like body of a contiguous modular contact box. The box-like body forms a central seat that accommodates a rotatable contact and two peripheral seats, each of which accommodates a connection portion of a corresponding fixed contact that can be accessed from the outside of the modular contact box. The rotatable contact is able to rotate about the axis of the central seat with respect to the box-like body in order to engage the fixed contacts arranged with their connection portion in the peripheral seats or to disengage from the fixed contacts.
