いという問題があった。As described above, the control switch 130 is large because it is composed of the substrate 131 and the push button type switches 132a to 132d. Therefore, the switch accommodating recess 110 must also be formed large, and
Assembling the control switch 130 is also complicated. A suction hose 140 is attached to the end of the gripping tube 100 on the cleaner body side (not shown), and an extension tube (not shown) is connected to the left end of the figure, and a floor brush (not shown) is attached to the extension tube. Are connected. And the cleaning is the grip 1
01a is gripped and cleaned. During this cleaning operation, since a large force is applied to the grip tube 100 downward in the drawing around the base part of the grip part 101a, a large force is applied to the grip part 100a at the base part of the grip part 101a. There is a problem that a crack is generated in the part and the part is broken from this part in some cases. The occurrence of this crack or breakage can be prevented by, for example, forming a reinforcing rib. However, as described above, the place where this reinforcing rib is formed is the switch housing recess 110 of the control switch 130.
Therefore, there is a problem that there is no space and the reinforcing rib cannot be formed.

し折損等が発生するという問題は解消できる。The above problem can be solved by using the above flexible printed circuit board switch as a control switch. That is, as shown in FIG. 7, a switch accommodating concave portion 221 is formed on the upper surface of the cover body 220 to form a switch accommodating concave portion 221 to form a switch mounting portion 222, and a control using a flexible printed circuit board switch is performed in the switch accommodating concave portion 221. The switch 223 is provided. By using the flexible printed circuit board switch as the control switch 223 in this way, the switch housing recess 221 can be formed with an extremely small space, so that the reinforcing rib 22 is formed on the lower surface of the cover 220.
4 can be formed at a desired portion, and a reinforcing rib (not shown) can be formed on the pipe side as well, so that the problem of cracks or breakage can be solved.

器においても発生するものである。However, in the flexible printed circuit board switch, the switch element consisting of the fixed contact (not shown) and the movable contact 225 provided opposite to the switch element and the resistor 226 as the signal generating element provided separately from the movable contact 225 are provided. It is provided on the same surface as and close to it. Therefore, the control switch 223 is attached to the bottom surface 22 of the switch housing recess 221.
When the movable contact 225 and the resistor 226 are arranged at the same position when the movable contact 225 is disposed at 1a, the resistor 226 may be erroneously pressed when the movable contact 225 is pressed. In addition, an external impact force may be applied to the resistor 226 by mistake during the cleaning or the storing operation. When a pressing force or an impact force is applied to the resistor 226 in this way, the connection portion of the resistor 226 is damaged and the control switch 22
3 causes a malfunction, and in some cases, the device itself is damaged. In such a switch, the frequency of the switch operation is high, so that there is a large chance that the resistor 226 is erroneously pressed at the time of this operation, and therefore the connection portion of the resistor 226 is damaged due to repeated pressing operations. Due to this, many malfunctions occur. This occurs not only in the electric vacuum cleaner described above but also in other electric devices.
