Motorcycle brake indicator light switch of the present utility model is characterized in that, comprising:

One takes over bolt, its head has a centre bore and to have the center transitional pore of arcwall, forms a shoulder between centre bore and the center transitional pore, and there are a center fuel feed hole and an oil outlet in its bar portion, the center fuel feed hole is connected with the center transitional pore, and oil outlet is connected with the center fuel feed hole;

One rubber diaphragm, it has an outer toroid part and a center curve face portion, and it is positioned at the centre bore of taking over bolt, and its outer toroid partly is pressed on the shoulder of taking over bolt, and center curve face portion is downward, facing to the center fuel feed hole of taking over bolt;

One cylindrical insulator, there is a ring-type convex shoulder its lower end, there is a blind hole at its center, two identical metal inserts are fixing symmetrically within it, metal insert has the upper end of wiring hole and stretches out from its upper end, stretch out from its lower end the lower end of metal insert, and it is positioned at the centre bore of taking over bolt, and the ring-type convex shoulder of its lower end is pressed on the outer toroid part of rubber diaphragm;

One circle metallic plate, it is placed on the part concave surface of rubber diaphragm, is positioned at the space of the ring-type convex shoulder encirclement of insulator lower end;

One back-moving spring, it is positioned at the central blind hole of insulator, and under the nature, the lower end of back-moving spring is pressed on the round metallic plate, and the lower end of the metal insert of insulator does not contact with the circle metallic plate.

Compare with the motorcycle brake indicator light switch of prior art, the advantage of motorcycle brake indicator light switch of the present utility model is:

Take over bolt and can be directly installed on the position of original adapter bolt, do not need reprocessing in addition that mating surface is installed, saved time and cost;

Bolt is a standard component, uses the adapter bolt of profile as the standard bolt shape, and the motorcycle brake switch of different model can exchange, and manufacturing enterprise does not need every kind of vehicle to be equipped with different spare parts, has reduced overstocking of fund;

Interchangeability is good, and is easy for installation, need not worry for buying less than first wife's model during maintenance.

Fig. 2 is the vertical view of motorcycle brake indicator light switch shown in Figure 1.

Embodiment

Below in conjunction with the drawings and specific embodiments motorcycle brake indicator light switch of the present utility model is described further.

As shown in Figure 1, motorcycle brake indicator light switch 1 of the present utility model comprises that one takes over bolt 2, a rubber diaphragm 3, an insulator 4, a circle metallic plate 5 and a back-moving spring 6.

The head of taking over bolt 2 has big centre bore 21, one a little centre bore 22 and to have the center transitional pore 23 of arcwall.Form a shoulder 24 between big centre bore 21 and the little centre bore 22.Form a shoulder 25 between little centre bore 22 and the center transitional pore 23.There is a center fuel feed hole 26 in the bar portion that takes over bolt 2.Center fuel feed hole 26 is connected with center transitional pore 23.There is an oil outlet 27 in the bar portion that takes over bolt 2.Oil outlet 27 is connected with center fuel feed hole 26.

Rubber diaphragm 3 has an outer toroid part 31 and a center curve face portion 32.Rubber diaphragm 3 is installed in the little centre bore 22, and the outer toroid part 31 of rubber diaphragm 3 is pressed on the shoulder 25, and curve face portion 32 in center is downward, facing to center fuel feed hole 26.

Insulator 4 is cylinders.There is a ring-type convex shoulder 41 insulator 4 lower ends.Insulator 4 has a central blind hole that Open Side Down 42.Two identical metal inserts 44 are fixed in the insulator 4 symmetrically, and metal insert 44 has the upper end of wiring hole and stretches out from the upper end of insulator 4, and stretch out from the lower end of insulator 4 lower end of metal insert 44.Insulator 4 is installed in the big centre bore 21 that is mated, and the lower surface of the ring-type convex shoulder 41 of insulator 4 lower ends is pressed on the outer toroid part 31 of rubber diaphragm 3.
