Is. Here, 20 is a case main body, 21 is an upper lid, 30 is an operator, 32 is a reversal drive unit, 40 is a movable contactor, 41 is a reversible drive unit, 42 is a movable contact, and 50 is a support piece.

First, the switch mechanism will be described.

The case body 20 has a box shape, and the case body 20 has an upper lid.
21 is put on. That is, the upper lid 21 is a lid stopper plate for the case body 20.
It is fixed by caulking the ends of 22. Case body
A terminal provided with a fixed contact 24 is disposed on the terminal 20, and the electric wire inserted from the electric wire insertion hole 25 is held by the pressing spring 26 on the terminal. Reference numeral 27 denotes a release button, and the electric wire can be removed by pressing the release button from the insertion hole 28 in the bending direction of the presser spring 28 with a screwdriver or the like.

An operator 30 is pivotally supported on the upper lid 21, and the operator 30 rotates about a rotation shaft 31. A movable contact 40 is provided below the operator 30.
An inversion drive unit 32 that engages with the inversion driven unit 41 is provided. In this embodiment, as the reversing drive unit 32, a groove 33 having a width slightly larger than the material thickness of the movable contact 40 is provided as shown in FIG. 7, and the reversing drive unit 32 and the reversal driven unit 41 are provided.
Ensures engagement with. Further, the reversing drive unit 32 of the movable contactor 40 provided in the lower portion of the operator 30 is provided so as to hang from the side wall of the operator 30 on both sides of the movable contact 42. With this configuration, when the indicator lamp is built in the operating element 30, it is possible to make the entire surface of the operating element 30 bright. Further, since it hangs down on both sides and is formed symmetrically, distortion such as kinking does not occur in the operator 30, the movable contact 40, and the like.

The movable contact 40 includes a reversible drive unit 41 that engages with the groove 33 of the operator 30 in the case body 20, a movable contact 42, and a movable contact 42.
A notch portion 43 formed in the vicinity, a bent portion 44 that is formed by bending the lower end of the movable contact 40 in a corrugated manner, and the bent portion.
It is formed of a connecting portion 45 that is connected to the connection portion 44 and is fixed to the connection terminal portion 23 at the bottom of the case body 20.

An engaging portion 46 is provided at the lower end of the movable contact 40 provided with the movable contact 42, and the engaging portion 46 is pivotally supported at a pivot point 51 of the support piece 50. The support piece 50 is disposed by inserting both ends of the M-shape into the groove of the inner bottom portion of the case body 20, pivotally supports the engaging portion 46, and slightly elastically deforms in the downward direction and the front-rear direction. The inner bottom portion of the case main body 20 allows a slight elastic deformation in the front-back direction of the support piece 50 and also a large amount of downward elastic deformation. The movable contact 42 is a fixed contact.
The switch is opened and closed reliably by facing 24.

Since the bent portion 44 is formed in the vicinity of the engaging portion 46 that engages with the pivotal fulcrum 51 of the support piece 50, which is the base point for the movable contact 40 to perform the reversing operation, the reversing operation width of the movable contact 40 is provided. Compared with this, it is possible to reduce the amount of elastic deformation of the bent portion 44, and since slight elastic deformation can be absorbed by the bent portion 44 that is bent in a waveform, it is possible to significantly extend the service life.

When the movable contact has a notch formed near the movable contact and the movable contact is configured to follow the swing of the inversion driven portion with a surplus force, it is possible to cope with wear and to touch the operator. First, the driven part swings and then the movable contact separates from the fixed contact, so it does not turn off immediately even if the operator is touched. There is no danger that ON / OFF will occur, an arc will fly between both contacts, and the contacts will wear and deteriorate the durability.

As described above, the engaging portion 46 provided at the lower end of the movable contactor 40 provided with the movable contact 42 and the engaging portion 46 provided at the inner bottom portion of the case body 20 are pivotally supported and elastic downward. A deformable support piece 50 and a bent portion 44 provided from the lower end of the movable contact 40.
And the connection terminal portion 23 is connected to form the reversal driving portion 32 provided on the operating element 30 and the reversal driven portion 41 provided on the engaging portion 46 of the movable contact 40. The movable contact 42 of the movable contactor 40 faces the fixed contact 24. Therefore, the reversing drive unit 32 of the movable contactor 40 provided on the operator 30
Moves on an arc around the rotation axis 31 of the manipulator 30. Further, the inversion driven part 41 of the movable contactor 40 inverts on an arc around the pivot point 51. By interlocking the reversal drive unit 32 and the reversal drive unit 41, the arc of the reversal drive unit 32 and the reversal drive unit 41
The amount of overlap with the circular arc of the fixed contact 24 is caused by the elastic deformation of the support piece 50 of the pivot point 51 in the downward direction and in the front-back direction.
And the movable contact 42 slides open and close. Moving contact 42 is fixed contact 24
Since it opens and closes while sliding, it is possible to reduce the occurrence of arcs, prevent contact welding when the switch is opened and closed, and also from this point, the life of the switch can be extended.
