Layout is used to transmit the device of excitation, makes at least one pressure spot of arranging not align with at least one row pressure force at least in part, and this is favourable, and like this, button can be provided with away from button row, and away from button can be provided with very showyly.

Advantageously, at least two pressure spots of the actuator of shell inboard and fore side are arranged substantially axisymmetrically.This provides following advantage, especially advantageously guarantees to encourage to the switch transmission equably, and more particularly, the transmission of excitation is to be independent of the pressure spot that has been energized in operator's side.

Desirable is that switch is arranged to a row on printed circuit board (PCB).

In further constructing, at least one switch is arranged on printed circuit board (PCB), makes this at least one switch be arranged in the alignment part outside of the switch that on the weld side of printed circuit board (PCB), becomes arranged at least in part.

It is favourable being arranged to a switch not in alignment with switch pair at least in part, and like this, a button can be provided with away from button row, and can be provided with very showyly away from the button that is provided with by this way.

Advantageously, parts and switch arrangement are at the not ipsilateral of printed circuit board (PCB), and wherein parts are bonded on this at least one switch, and the feed line of parts is arranged on the not homonymy of this switch.

Because the free space size on the printed circuit board (PCB) is usually very limited; So on the side of printed circuit board (PCB) and be especially favourable on for example with the another side of arrangements of components at printed circuit board (PCB), this can provide bigger freedom aspect wires design with this at least one switch arrangement.Become to make the feed line that is used for parts at ipsilateral not arrangements of components; That is to say, for example be arranged in top and bottom or the left side and the right of switch, that is to say to be bonded on the switch; Mean that circuit arrangement can further optimize, the required space of circuit structure can also reduce in addition.Preferably, switch arrangement is in the weld side of circuit board, and arrangements of components is at the parts installation side of circuit board.

Terms part is used to represent simple electronic unit and power part.

In especially favourable improvement, the device that is used to transmit excitation is held in a side.Transfer device is supported in a side and makes and simply to create possibility, has also reduced the susceptibility to fault in addition.

In preferred alternative, the configuration that is used to keep to transmit the device of excitation is film hinge or 2 retainers.

In favourable improvement, the retainer that is used to transmit the device of excitation is tongue or sheet spring.The form of transfer device being processed tongue or sheet spring is especially favourable, like this, during making shell, needn't the SC strength of materials.

In a further embodiment, actuator does not have pin, perhaps is formed with pin.The special advantage of not having the pin actuator is that the shell manufacturing is especially simple.The advantage that the pin actuator is arranged is that switching characteristic strengthens.

Advantageously, shell has single part (one-part) character with the device that at least one is used for the excitation of transmitting control device.The single part formula design structure of shell and transfer device is allowed with the one-stop operation operational example as through injection-molded cheap manufacturing.
