The height of described adjustment contact, higher than the height of contact bridge working face, facilitates the contact on rear cover assembly to touch.
Described flexure strip is by rivet on contact bridge body, and technique is simple.
The beryllium-bronze that described flexure strip is 0.2 ~ 0.4mm by thickness is made, thinner beryllium-bronze has certain elasticity, and when adjusting contact and being pressed onto by the contact contact on rear cover assembly, flexure strip can bend, when adjustment contact does not stress, flexure strip can restore to the original state.
Described 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.When the contact contact on rear cover assembly is after certain hour uses, wearing and tearing in various degree can occurs, arrange this dead slot and can guarantee when ST shelves, four contact contacts can not cannot be in one plane because of wearing and tearing.
Five contact contact heights on described rear cover assembly are identical, and different contact contacts realizes different gear by the contact of contact bridge working face.
The present invention also comprises key, lock core and moving block, and described key is arranged in lock core, and lock core is connected with moving block, and moving block is connected with contact bridge assembly by rotatable interface.
Described lock core is provided with protective cover, and after key is extracted, lock core can cover by protective cover, plays the effect of sealing.
Described moving block, contact bridge assembly and rear cover assembly outer cladding are provided with rubber guard shield, prevent external dust and foreign matter from sticking to switch external, can well protect the insulating properties of each contact point, avoid switch short.
The present invention has the following advantages compared to existing technology: ignition switch of the present invention improves the disposable qualification rate of production, solves the present situation that failure rate is after sale high, realizes dustproof and waterproof simultaneously, improves life of product.
