Buttons (41A, 41B) have a button moving part (42) disposed in front of a circuit board (51) and allowed to move in a front-back direction, and guided parts (42e) moving in conjunction with the button moving part (42). The buttons (41A, 41B) cause the button moving part (42) to operate a switch (52) of the circuit board (51). Guide parts (21E, 21F) are disposed along the guided parts (42e) and restrict the direction in which the button moving part (42) moves. The guide parts (21E, 21F) and the guided parts (42e) have portions located back of a front surface (51a) of the circuit board (51). This structure effectively prevents the buttons from tilting when they are operated.

The force sensing dome switch is configured to simultaneously, or nearly simultaneously, close or open two separate circuits. For one of these circuits, the force sensing dome switch acts as a variable resistor whose value is controlled by applied force. Each force sensing dome switch is disposed upon a printed circuit board (PCB) comprising two separate circuits. An example force sensing dome switch comprises: a conductive dome in conductive contact with a first trace of a first circuit, the conductive dome is configured to make conductive contact with a second trace of the first circuit when pressed down; and a force-sensing resistor element positioned between the PCB and the conductive dome, the force-sensing resistor element overlays a pair of traces of a second circuit and is configured to conductively connect the pair of traces when pressed against the PCB by the conductive dome. The force-sensing resistor element is a layer of material whose resistance changes when force is applied.

The invention relates to an electrical switch (30) for an electrical appliance (2), in particular for a power tool, which has at least two switching contacts (34, 36), which can be jointly moved between a switched-off position (38), in which the switching contacts (34, 36) have no electrical connection to a counter contact (42) of the switch (30), and a switched-on position (40), in which the switching contacts (34, 36) are electrically connected to the counter contact (42). To maintain a contact resistance of the switch (30) at a largely constant value over the service life, it is proposed to arrange and/or design the switching contacts (34, 36) and/or the counter contact (42) such that, when the switch (30) transitions between the switched-off position (38) and the switched-on position (40), the switching contacts (34, 36) successively enter into electrical contact with the counter contact (42) or successively break the electrical contact.

The first circuit board assembly comprises a first printed circuit board and at least two switch circuits disposed on the first printed circuit board. The magnetic core assembly is disposed near the first printed circuit board and comprises a magnetic core portion and at least one pair of first electrical conductors. The magnetic core portion comprises at least one core unit, the core unit comprises a pair of holes and a second magnetic overlapping region, and the pair of holes are separated by the second magnetic overlapping region. Each pair of the first electrical conductors is penetrated through the corresponding pair of holes of the magnetic core portion to define two output inductors. Each of the switch circuits is electrically connected with the corresponding output inductor to define a phase circuit of the power module.

A power module includes a power source module and a metallic heat-dissipation substrate. The power source module has an input pin and an output pin soldered on and electrically connected with a system board and includes a printed circuit board. The printed circuit board has a first surface and a second surface. At least a heat-generating component is disposed on the second surface. The metallic heat-dissipation substrate has a first surface and a second surface opposite to each other. The first surface has at least a fixing position and at least a heat-dissipating position. The fixing position is directly or indirectly connected with the second surface. A gap accumulated by tolerances is existed between the heat-dissipating position and the heat-generating component. A gap-filling material is filled into the gap. The second surface and the system board are soldered with each other. Therefore, the heat-dissipation efficiency is enhanced.
