On the other hand, the setting of gap 4 and oil groove 3, makes copper scale, carbide and other impurity fall in oil groove 3 when sliding, and reduces greatly because the electric discharge ablation probability of generation is touched in virtual connection, thus improves the useful life of rocker switch from another angle.
Described contact piece 2 has recess near described convex tendon 3a side, and described gap 4 is positioned at described indent, and the side of described boss 3a aligns with the side of described contact piece 2.
This optimal technical scheme is provided with recess, and is arranged in recess by described gap, makes conductive plate 5 leave convex tendon 3a, almost the spot film 2 of contact contact simultaneously, because contact piece 2 and convex tendon are in sustained height, so reduce further the generation of kick sense.If because do not arrange this recess, then when conductive plate 5 slips over described gap 4, a little kick sense still certainly will be had.
Described gap 4 width need be more than or equal to 0.5mm.
On described conductive plate 5, the width of double-contact 5a equals the width of described contact piece 2.
Beneficial effect of the present invention is:
1) by the setting of oil groove, add the memory space of electronics lubricating oil, enhance lubrication, slow down the ablation of electric arc to contact piece, thus extend the useful life of Rocker switch for vehicle.
2) impurity is dialled and is dropped down onto in oil groove by conductive plate slip, thus greatly strengthen the stability of contact, avoids contact and produces ablation because virtual connection is touched, extend the useful life of Rocker switch for vehicle from another angle.
3) tank structure design is ingenious, overcomes the technical difficulty of kick sense completely.
4) there are the market prospects extensively promoted.
