Claim 15:
16. The battery-powered portable tool according to claim 15, further comprising:
a bimetal or bimetal strip configured to switch the plurality of components between the first physical configuration and the second physical configuration and vice versa by changing from a first shape to a second shape and vice versa in accordance with a change in 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 physical configuration to the second physical configuration and vice versa, is between −5° C. and +50° C., and
the bimetal or bimetal strip is configured to cause:
the heat-dissipation-required component to be spaced apart from the heat-dissipating member while the temperature is equal to or lower than the first boundary temperature and the bimetal or bimetal strip has assumed the first shape, and
the heat-dissipation-required component to directly contact the heat-dissipating member while the temperature is equal to or higher than the second boundary temperature and the bimetal or bimetal strip has assumed the second shape.
