Claim 7:
8. The battery-powered portable tool according to claim 7, further comprising:
a bimetal or bimetal strip configured to switch the plurality of components between the first layout and the second layout by changing its shape between a first configuration and a second configuration and vice versa in accordance with temperature; and
a heat-dissipating member,
wherein:
the temperature range, in which the plurality of components is switched by the bimetal or bimetal strip from the first layout to the second layout and vice versa, is between −5° C. and +50° C., and
the bimetal or bimetal strip is configured such that:
the heat-dissipation-required component and the heat-dissipating member are in a noncontacting state in the first configuration due to the temperature being equal to or lower than the first boundary temperature, and
the heat-dissipation-required component and the heat-dissipating member are brought into contact in the second configuration due to the temperature being equal to or higher than the second boundary temperature.
