The invention relates to a program switch for mounting on a printed circuit board comprising a housing, an insulator component with contact elements arranged thereon, and a switching element for contacting the contact elements. The housing has at least two connection elements for connecting the program switch to adjacent program switches to form a program switch arrangement having an arbitrary number of poles. Production and stock keeping and sale of the program switch are simple.

An auxiliary switch includes a housing including a first housing part and a second housing part separate from and releasably connected to the first housing part. A printed circuit board is fixedly mounted within the housing and has an electrical pad and an electrical contact connected to the electrical pad. A terminal conductor is electrically connected to the printed circuit board. An actuator mechanism is mounted within the housing and has an electrical contactor engaged to the terminal conductor. The actuator mechanism is configured to move within the housing and at least partially displace the electrical contact while maintaining engagement between the contactor and the terminal conductor.

First guide supports and second guide supports are integrally formed on an external base material to which external terminals are fixed. Guide protrusions and guide concave parts, which extend vertically, are formed on the housing of a switch device. When each guide protrusion and its corresponding guide concave part are guided by a first guide support and a second guide support during the attachment of the switch device to the external base material, the switch device can be easily attached.

An electronic-component-protection structure which can protect, with a simple configuration, an electronic component from static electricity that may be charged in a case member. A ground member having conductivity is integrally formed with a circuit board or electrically connected to the circuit board, wherein the circuit board has an electronic component mounted thereon. A housing includes a base member and a case member and accommodates the circuit board and a ground member. A sealing member, which is a conductive elastic member disposed between the base member and the case member, is at least partly exposed to the outside of the housing.

Disclosed is a wall-mounted device, which is mainly provided with a base and a cover plate, and the at least one module circuit board is provided in the cover plate. The power terminal of at least one module circuit board is electrically connected to an exterior live wire circuit of the base, so the interior live wire circuit is able to independently supply power to the module circuit board of the cover plate. As the result, the base is able to fit or replace with any cover plate provided with module circuit board, and connects to any electronic device or network to remotely control and operate.

A carrier for electrical and/or electronic components is provided, in particular, a printed circuit board, having a broadside for accommodating electrical conductor tracks, and having a narrow side. At least one electrically conductive contact area is provided on the carrier, the contact area, in particular, being used as a fixed contact for an electrical switch. The contact area is arranged on the narrow side.

A printed circuit board (PCB)-mounted contactor including a PCB with planar surface, source and load terminals fixed to the PCB, and a contact. The contact is supported by the PCB and is movable between open and closed positions. Movement of the contact is parallel to the planar surface. Electrical assemblies having PCB-mounted contactors and methods of controlling current flow in electrical systems with PCB-mounted contactors are also described.

A switch may include a movable board and a pole board having an inner surface on which a fixed contact point is exposed, the inner surface facing the movable board. A movable contact point may be supported by the movable board and may include a plurality of contact pieces making resilient contact with the inner surface of the pole board. The switch may also include an output terminal corresponding to the fixed contact point. The movable contact point and the fixed contact point may come in contact with each other when a position of the movable contact point is changed via a displacement of the movable board. The fixed contact point and the output terminal may be connected via a board having a disconnection detection circuit. The board may be enclosed in an insulating seal material.

An electrical device such as, for example, a battery-powered electrical switch is disclosed. The battery-powered wireless switch includes one or more mechanisms arranged and configured to provide simplified access for servicing (e.g., replacing) the batteries located within the wireless switch. In one embodiment, the wireless switch is arranged and configured so that the batteries may be accessed by reconfiguring the wireless switch from a first closed position to a second opened position to access the batteries. Thus arranged, removal of the wireless switch from a wall-box or a surface of a wall is not required, the user may only need to remove the wall-plate in order to reconfigure the wireless switch. In one embodiment, at least a portion of the wireless switch is pivoted from the first position to the second position to provide access to the batteries.

A relay includes a movable block, a base substrate, and a coil block. The movable block is provided rotatably around a rotational axis of the movable block. The movable block includes a plurality of sliders. The base substrate is disposed opposite the movable block in the rotational axis direction of the movable block, and contacts the sliders. The base substrate includes a plurality of contactors that come into contact with the sliders. The coil block includes a coil that generates electromagnetic force by electric conduction to rotate the movable block with respect to the base substrate. As the movable block rotates, continuity is switched between the sliders and the contactors.
