Rotary switches and associated methods. A rotary switch can include one or more arcuate passages which are prone to ingress of particulate or liquid contaminants. A gasket, a rib, and/or a lubricant reservoir can be provided in the arcuate passages for blocking ingress of contaminants to an interior of the switch.

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.

An illuminated push-button switch according to the present invention includes a key top, a plunger, and a supporting fix member that forms a space between the key top and the plunger, and supports and fixes together the key top and the plunger. A plurality of the supporting fix members are provided, separated from each other, in a plane perpendicular to an optical axis. With this configuration, the illuminated push-button switch having a wide illuminated region secured on a touch surface, and a keyboard can be provided.

According to various embodiments, an electronic device comprises a key button that can be assembled to keep the key button in place in the housing of the electronic device and functional without having to completely assemble the housing of the electronic device.

A circuit board enclosure comprises a circuit breaker, platform, base, cover, and circuit board. The circuit breaker includes two conductors and a plate, which is connected to the conductors. The platform receives the circuit breaker. The base has a bottom member and an opening arranged in the bottom member. The base receives the platform with the circuit breaker such that the plate of the circuit breaker is accommodated substantially within the opening of the bottom member. The cover is configured to cover the base and form an interior space. The interior space accommodates the platform, the circuit breaker, and the circuit board. The circuit board is connected to the circuit breaker. The circuit board enclosure can be adhered to a substantially planar surface. The plate is configured such that removal of the circuit board enclosure from the substantially planar surface will damage the connection of the plate to the conductors.

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.

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.

A safety switch for guarding accesses to industrial machines or plants comprises a case which extends along a main dimension defining a longitudinal axis of development, control means housed in the case and suitable for receiving and exchanging signals with the actuating device and/or with the machine or plant and provide with a first PCB, a head connected to the case and adapted to interact with the actuating device upon the opening/closing of the access and wherein the first PCB comprises a first longitudinal portion housed in the case and a second longitudinal portion housed in the head.

A reed switch relay comprises a PCB base (1) and a control assembly (2) electrically connected to the PCB base. The control assembly is mounted on the PCB base by a surface mount technology. The control assembly comprises a hollow coil (21) mounted on the PCB base, a reed switch (22) mounted in the hollow coil, and a shield layer (23) sleeving the outer surface of the hollow coil, the reed switch comprises pins, the shield layer is connected with the pins of the reed switch. In the reed relay, the control assembly is mounted on the PCB base though a surface mount technology, which ensures position tolerance and precision of the reed switch, implements full mechanization of product production, increases productivity, and satisfies requirements of mass production, thereby increasing economic benefits.

An electronic device includes a substrate having a top surface, a bottom surface and at least one opening therethrough. The substrate has a circuit. A switch mechanism is mounted to the substrate and is electrically connected to the circuit. The switch mechanism has an actuator configured to activate the switch mechanism. The switch mechanism has a housing holding the actuator and leads extending from the housing. The leads are electrically connected to the circuit. The switch mechanism is mounted to the substrate in the opening such that at least a portion of the housing is positioned below the top surface.
