う問題がある。When such a conventional switch is used in an inverter lighting fixture having a capacitor in its circuit, the rush current when the switch is turned on is about 500 A, which is much higher than that of an incandescent lamp. Since it is high and its peak is about 0.2 msec, there is a problem in that minute opening and closing is performed due to a bounce (chattering) phenomenon when the switch is turned on, contact wear is remarkable, and contact life is extremely shortened.

In the figure, g indicates the minute gap at this time. The time for which the open / close body 7 is turned off by the bounce is shown in FIG.
As shown in No. 1, it is between 0.2 and 0.4 msec.
After that, as shown in FIG. 20, the opening / closing body 7 loses the bounce, and the contacts 5 and 6 are closed again to be in a steady state (switch-on).

In the same figure (b), between times t 1 and t 2 , the contacts 5 and 6 are opened almost in synchronization with the mechanical bounce, and a current flows through the arc. The arc melts the contact, welds it, or consumes the contact violently. The energy during this period is expressed by Equation 1.

Form a slit 37 in the center of the flexure 4a of the strip 4.
Form, the fixed contact width D 2 of the bending portion 4a of the tether 4
By making the width narrower than the width D 1 of the portion 4b , or
As shown in FIG. 11, cut at the side end portion of the flexible portion 4a of the connecting piece 4.
Forming the notch 40, the width D of the flexible portion 4a of the connecting piece 4
5 (D 3 + D 4 ) is narrower than the width D 1 of the fixed contact 4b.
In any case, the spring of the connecting piece 4
It is possible to lower the constant, so it is easy to bend the connecting piece 4.
It can be opened and closed by reversing the opening and closing body 7.
The movable contact 6 of the body 7 urges the fixed contact 4b of the connecting piece 4.
Opening / closing body 7 even when the switch is turned on due to frequent collisions
The connecting piece 4 can be bent by the recoil when the opening / closing body
The connecting piece 4 absorbs the impact at the time of rushing in 7, and the opening / closing body 7
It is possible to prevent the rebound caused by the recoil. 12
This is a case where the connecting piece 4 is formed thin by press working. In this case, the thickness C 2 of the flexible portion 4a of the connecting piece 4 is
It is thinner than the thickness C 1 of the main body 2a of the fixed terminal board 2.
It FIG. 13 shows an embodiment in which the connecting piece 4 is formed thin and the width thereof is narrower than that of the contact 5. This
The bending of the main body 2a of the fixed terminal board 2 and the connecting piece 4
A step in the thickness direction is formed between the portion 4a and the connecting piece 4

The connecting piece 4 is lengthened to lower the spring constant k. Here, the lower portion 2c of the main body 2a of the fixed terminal board 2
The distance L 2 from the movable contact 6 of the opening / closing body 7 to the fixed terminal plate
2 from the upper part 2d of the main body 2a to the movable contact 6 of the opening / closing body 7.
If it is set longer than the distance L 1 of
Do not attach the piece 4 from the upper part 2d of the main body 2a of the fixed terminal board 2.
The fixed contact 5 by protruding from the lower part 2c.
The connecting piece 4 without changing the relative position to the movable contact 6
From the connection with the fixed terminal plate 2 to the fixed contact point 4b.
That the length (L 2 -L 1) Yes be extended only longer
Therefore, in the above point A configuration, the flexible portion 4a
Of the connecting piece 4 whose width is narrower than that of the fixed contact portion 4b
The constant is further reduced by lengthening the connecting piece 4,
When the opening / closing body 7 is rushed in, the gripping piece 4 becomes easier to bend.
The impact is absorbed by the connecting piece 4 and is caused by the recoil of the opening / closing body 7.
Bounce can be prevented more reliably. Moreover, the fixed contact 5
It is not necessary to change the relative position between the movable contact 6 and
Changing the protruding position of the connecting piece 4 from the main body 2a of the child board 2
Just change the design of the switch mechanism.
Extend the length of the connecting piece 4 longer and more easily
Is something that can be done.
