ものである。 As shown in Fig. 1, a conventional emergency foot switch has a side surface C of an operation button cover B provided integrally with a cover A.
By protruding the operating button D and moving the operating button in the P direction with your foot, you unlocked the cover A, and the weight of your foot lowered the cover A, activating the built-in switch. While cleaning the mop, there was a risk of accidentally moving the operating button in the P direction with the mop. The present invention aims to improve the above-mentioned drawbacks, and includes a switch in a container consisting of a base, a cover having a recess larger than the outer shape of the base, and one end of which is fixed to the base. In a foot switch in which the cover is lowered by the force applied to the cover when the lock is unlocked and the switch is actuated, the foot switch has a hole through which the operation surface of the operation button for unlocking the cover faces. The emergency foot switch has an operation button cover provided in front of the switch that protrudes from the cover, and a shoe-tip notch connected to the hole through which the operation surface of the operation button faces on the upper surface of the operation button cover. It is something.

ある。 Reference numeral 1 denotes a base made of thermoplastic resin, which has a recess 2 and is connected to a cover 4 at a thin wall portion 3. The cover 4 is integrally formed with a recess 5 larger than the outer shape of the base 1 and an operation button covering part 7 that covers the operation button 6.
Reference numeral 8 denotes a switch that is housed and fixed in a vacant space formed by the recess 2 of the base 1 and the recess 5 of the cover 4, and the push button 9 is connected to the bottom surface 10 of the recess 5 of the cover 4, leaving a slight gap. They are facing each other. The operation button 6 includes an operation surface 11 and a protrusion 15 that comes into contact with a circular protrusion 14 of the cover 13 that forms a hole 12 through which the push button 9 of the switch 8 appears. It is locked. Reference numeral 17 denotes a spring which is attached to the side wall 7 of the operation button cover 7 so that the operation surface 11 of the operation button 6 can be seen through the hole 7c provided in the side surface of the operation button cover 7.
The spring is locked between a and the operation button 6. Reference numeral 18 denotes a shoe tip-shaped notch provided on the upper surface of the operation button covering portion 7. The switch 8 has a push button shaft 19 that is pushed upward by a return spring 18, a contact spring 21 that is operated by an operating protrusion 20 provided on the push button shaft 19, and another contact spring 22 that is in contact with the contact spring 21.
, elastic bodies 24, 24 that come into contact with the protrusion 23 so that the push button shaft 19 is not returned by the return spring 18 when it is lowered, a push button shaft stopper 25 that comes into contact with the inner surface of the cover 13, and the operation button 9. It is.

は下降しないのである。 Then, place your foot on the foot tread surface 4a of the cover 4,
When pushed in the P direction, the protrusion 15 of the operation button 6 no longer comes into contact with the circular protrusion 14, and the weight of the foot causes the cover 4 to descend, causing the bottom surface 10 of the recess 5 of the cover 4 to lower the push button 9 of the switch 8. . When the push button 9 descends, the contact spring 21 is deflected downward by the operation protrusion 20 and comes into contact with the contact spring 22 to close the contact circuit, and the protrusion 23 is positioned below the elastic bodies 24, 24, and the force of the return spring 18 is increased. In this case, it does not return upward and remains closed. Although the dimension H of the operation surface 11 of the operation button 6 is smaller than the height dimension h of the shoe, a shoe tip-shaped notch 18 is provided on the upper surface of the operation button cover 7 so as to be continuous with the hole 7c. , so the shoes can move smoothly in the P direction. On the other hand, even if the mop is mistakenly placed on the operation surface of the cover 4 and a force is applied in the P direction, the protruding dimension a of the operation button 6 is very small, and the operation button 6 hits the sides 7b, 7b of the operation button cover 7. Projection piece 15
remains in contact with the circular protrusion 14, and the cover 4 remains in contact with the circular protrusion 14.
does not fall.

チが得られ実用上有効である。 As described above, according to the present invention, a switch is provided in a container consisting of a base and a cover having a recess larger than the outer shape of the base and one end of which is fixed to the base, and when the cover is unlocked, In a foot switch in which the cover is lowered by a force applied to the cover to operate the switch, a hole is provided in front of the foot surface of the cover through which the operation surface of an operation button for unlocking the cover faces. The operation button cover is formed to protrude from the cover, and the top surface of the operation button cover is provided with a shoe tip-like notch that is connected to the hole through which the operation surface of the operation button faces, making it easy to operate the emergency foot switch. If the operation button 6 comes into contact with the sides 7b, 7b of the button cover 7 and cannot be moved sufficiently in the P direction, it will not malfunction. Since there is a tip-shaped notch 18, the operation button can be smoothly moved in the P direction, the cover is unlocked, the cover 4 is lowered by the weight of the foot, and the switch 8 can be operated. Further, since the cover 4 is normally locked, it is possible to obtain an emergency foot switch that is less likely to malfunction, such as not being activated simply by placing the foot on the foot surface 4a of the cover, and is thus practically effective.
