A switch for a power tool, the switch including a printed circuit board and a silicone layer. The printed circuit board has a first microswitch, while the silicone layer has a blocking switch, the silicone layer being present arranged on the printed circuit board such that an actuation of the blocking switch leads to an actuation of the first microswitch. Furthermore, the printed circuit board can have a second microswitch, and the silicone layer can have a membrane, an actuation of the membrane leading to an actuation of the second microswitch. A method for switching on a power tool, the power tool including a switch having a printed circuit board and a silicone layer. An ergonomically advantageous switch is also provided, which switch is furthermore well protected against dust, dirt and/or water and enables inadvertent switching on of the power tool to be effectively avoided.

An electronic control device may be configured to be integrated, or coupled, with a bicycle to control bicycle components. The electronic control device may wirelessly control bicycle components to trigger an action when actuated. The electronic control device may be dimensioned to have a mating surface contoured to matingly engage with a mounting surface of a bicycle, such as on a handlebar. The electronic control device may also be dimensioned to have a compact and/or concealed appearance aided by a low profile relative to the bicycle mounting surface selected for the control device.

An obstruction detecting apparatus, an obstruction detecting system, an electric lifting desk, and an electric lifting cupboard, which relate to the field of obstruction detection and render a higher obstruction detection sensitivity. The obstruction detecting apparatus includes a first housing and a second housing, the second housing being floatingly mounted on the first housing via a first elastic member, on the first housing being provided a circuit board, an obstruction detecting switch connected to the circuit board, and a rocking element rotatably mounted, one end of the rocking element being a free end abutting against the first housing, opposite end of the rocking element being a pressing end pressing down on the obstruction detecting switch, the free end, when being rotated, driving the pressing end to be disengaged from the obstruction detecting switch, whereby an obstruction signal is generated.

An electric switch has a housing with an upper surface through which a actuating plunger extends at a position close to a side surface. The actuating plunger is arranged to operate a switching element disposed inside the housing. An actuating lever is fixed to the side surface adjacent the plunger such that the actuating lever extends over and beyond the upper surface of the housing. A stop for the actuating plunger is arranged inside the housing. With this switch the actuating travel is extended solely in relation to the switch. Furthermore a long over-travel exists following switching, wherein any forces which might occur through improper use in relation to the switch do not cause any damaging effects to the switching element.

A pressure compensating button can include a depressible interface. The depressible interface can define an external surface of the electronic device. The button can include a tactile switch. The button can include a first pressure accumulator, such as a first piston or plunger. The first pressure accumulator can be associated with the depressible interface. The first pressure accumulator can be configured to receive a first hydrostatic pressure. The button can include a second pressure accumulator, such as a second piston or plunger. The second pressure accumulator can be configured to receive a second hydrostatic pressure. The second pressure accumulator can counteract the first pressure accumulator, such as via a mechanical linkage, to limit an actuation of the tactile switch via the first hydrostatic pressure. Additional systems and methods are also disclosed.

An image forming apparatus including a housing, a cover, an interlock switch, a locking assembly, and a biasing assembly. The housing may comprise a pair of frames spaced apart from each other, and may form an opening between the pair of frames. The cover may move between a covered position wherein the opening is covered and an opened position wherein the opening is uncovered. The interlock switch may be pressed by the cover when the cover is in the covered position. The locking assembly may move between a locking state wherein the locking assembly locks the cover in the covered position and a released state wherein the locking assembly allows the cover to move. Further, the biasing assembly may be positioned in or on at least one of the frames, and may bias the cover toward the opened position when the cover is in the covered position.

A printed circuit board, PCB, based connector for connecting at least one wire to at least one microswitch in a position sensor for a motorised valve assembly is provided comprising a PCB comprising at least one first through hole and at least one second through hole. The at least one first through hole is configured to receive a solder pin of at least one microswitch. The at least one second through hole is configured to receive at least one wire and the PCB further comprises a slot configured to receive the at least one wire with an interference fit.

A switch comprising a printed circuit board assembly, PCBA, including a printed circuit board, PCB, and a stationary contact; a cap in contact with the PCB such that the cap and the PCB define a switch chamber for the stationary contact, the cap carrying a movable contact, the cap being arranged to be deformed from a disconnected state where the movable contact is separated from the stationary contact to a connected state where the movable contact contacts the stationary contact, and the cap being forced towards the disconnected state; an actuator movable relative to the stationary contact between an activated position where the actuator pushes the cap to the connected state, and a deactivated position allowing the cap to be forced to the disconnected state; and a potting compound enclosing the PCB and the cap. A lock device comprising a switch is also provided.

An actuator switch includes a first switch member is movable from an inactivated position to a first toggle position in a first direction and a second toggle position in a second direction and a third toggle position in a third direction transverse to the first and second directions and a fourth toggle position in a fourth direction opposite the third direction. A first switch member is movable from an inactivated position to a first position in an upward direction and a second position in a downward direction. A keypad includes a first group of two electrical contacts each associated with the second switch member and a second group of four electrical contacts each of which is associated with the first switch member.
