On the contact bridge body, technology is simple through rivet for said flexure strip.
Said flexure strip is that the beryllium-bronze of 0.2～0.4mm is processed by thickness; Thin beryllium-bronze has certain elasticity, and when the adjustment contact was pressed onto by the contact contact on the rear cover assembly, flexure strip can be crooked; When not stressing on the adjustment contact, flexure strip can restore to the original state.
Said contact bridge working face is provided with the dead slot that groove depth is 0.3～0.5mm, and through hole is positioned at dead slot.After use through certain hour the contact contact on the rear cover assembly, wearing and tearing in various degree can take place, this dead slot is set can guarantees when the ST shelves, four contact contacts can can't be not in one plane because of wearing and tearing.
Five contact contact heights on the said rear cover assembly are identical, and different gears are realized through the contact of contact bridge working face in different contact contacts.
The utility model also comprises key, lock core and moving block, and said key is arranged in the lock core, and lock core is connected with moving block, and moving block is connected with the contact bridge assembly through rotatable interface.
Said lock core is provided with protective cover, and after key was extracted, protective cover can cover lock core, played the effect of sealing.
Said moving block, contact bridge assembly and rear cover assembly outsourcing are covered with the rubber guard shield, prevent that external dust and foreign matter from sticking to switch external, can well protect the insulating properties of each contact point, avoid the switch short circuit.
The utility model is compared prior art and had the following advantages: the ignition switch of the utility model has improved the disposable qualification rate of production, has solved the high present situation of failure rate after sale, realizes dustproof and waterproof simultaneously, improves life of product.

Embodiment
Embodiment in the face of the utility model elaborates down; Present embodiment is being to implement under the prerequisite with the utility model technical scheme; Provided detailed execution mode and concrete operating process, but the protection range of the utility model is not limited to following embodiment.
Like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, present embodiment key 1, lock core 2, moving block 3, contact bridge assembly 4 and rear cover assembly 5, contact bridge assembly 4 comprise contact bridge body 41, contact bridge working face 43, flexure strip 44 and adjustment contact 42; On the front that is arranged on contact bridge body 41 of contact bridge working face 43 convexities; Flexure strip 44 is positioned at the back side of contact bridge body 41; One end of flexure strip 44 is fixed on the contact bridge body 41; The other end is fixedly linked with adjustment contact 42, and adjustment contact 42 is positioned on the contact bridge working face 43, and on the contact bridge working face 43 and 42 corresponding positions, adjustment contact are provided with and are used to adjust the through hole that contact 42 is passed; Rear cover assembly 5 is used with contact bridge assembly 4, and the mid portion of contact bridge assembly 4 is provided with rotatable interface 46, and rear cover assembly 5 is provided with five contact contacts.
