[Background technology]

The mainstream switch for electric shavers is a slide switch, but in recent years electric shavers that are equipped with a switch for switching between a spare battery and a spare battery, etc. There are many problems with the switch. That is, if a single slide operator is used to turn on and off a plurality of switches, the amount of operation of the slide operator must be increased, which poses a problem in terms of usability. Furthermore, as shown in FIG. 13, there are slide controls 2', 3', 4', these slide operators operate independently, so if you want to return to the original state after using it with multiple switches, for example, each slide operator must be operated individually. You have to operate it, and it is not easy to use. Furthermore, with a slide switch, the operating space for the slide operator is inevitably large, so
It is difficult to arrange each slide operator in a position where it is easy to operate, and even if it were possible to do so, the electric shaver would become larger due to the above-mentioned operating space.

[Purpose of the invention]

The present invention has been made in view of these points, and its purpose is to provide an electric shaver with excellent operability despite having a plurality of switches for multifunctionality. It is in.
