Description
Technical field
The utility model relates to a kind of sensitive switch.
Background technology
At present, existing sensitive switch has generally included shell body, in described shell body, correspondence is provided with a movable contact spring and two static contacts, every block static contact is all fixed with a fixed contact, and two fixed contacts on two static contacts are upper and lower symmetry arrangement, one end of described movable contact spring to extend between two fixed contacts and is equiped with moving contact, the other end of described movable contact spring is then directly connected with button, due in the prior art, described movable contact spring is strip structure, therefore the gap not only causing like this filling between moving contact thereon and fixed contact is less, in use move, fixed contact is easily sticked together, easily produce spark in the energized state like this, even cause security incident, and also there is intensity difference and the inadequate defect of elasticity in the movable contact spring of strip, existing movable contact spring is all directly be connected with button simultaneously, therefore also there is the not good defect of pressing feel in existing sensitive switch.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of more reasonable structure, uses safer and effectively can improve the Large space sensitive switch pressing feel.
For achieving the above object, the utility model provides a kind of Large space sensitive switch, comprise shell body, in described shell body, correspondence is provided with a movable contact spring and two static contacts, every block static contact is all fixed with a fixed contact, and two fixed contacts on two static contacts are upper and lower symmetry arrangement, an extension spring and a support is also provided with in described shell body, described static contact and support are all fixed on shell body, on the two sides of described support, symmetry offers bayonet socket, one end of described movable contact spring is provided with two pins be symmetrical set, each pin is all located in a bayonet socket, and the inner side of described pin also corresponding offering form the hinged breach coordinated with described bayonet socket, the other end of described movable contact spring is provided with the bending extension block bending and extend between two fixed contacts, and correspondence is provided with the moving contact suitable with described fixed contact on described bending extension block, described movable contact spring also offers formed to hook with one end of described extension spring and join fixing movable contact spring through hole, described support is provided with a projection, on described projection corresponding offer to be formed to hook with the other end of described extension spring join fixing projection through hole, described extension spring is also provided with by realizing dynamic to its pressing, the press device of fixed contact adhesive or disjunction.
The beneficial effects of the utility model are: adopt said structure, because the utility model has set up bending extension block on described movable contact spring, and make described moving contact be installed on described bending extension block, therefore the gap between moving contact and fixed contact is greatly expanded, thus make the use of sensitive switch more safe and reliable, compared to existing technology simultaneously, intensity and the elasticity of movable contact spring also strengthen greatly, in addition, described press device acts in extension spring, then movable contact spring action is driven by extension spring, the elasticity of movable contact spring and the overall sense of touch of sensitive switch can be increased so further, thus the pressing feel of sensitive switch is effectively improved.
The utility model can be set to described press device further and include pressing contact and pressing plate, one end of described pressing plate is provided with the lug be hinged with described shell body, the other end of described pressing plate is resisted against on the outer end of pressing contact, and the inner of described pressing contact is then connected with extension spring.Adopt above-mentioned setting, structure is simple, easy and simple to handle.
The utility model also can be set to be connected by arc-shaped transition block between described movable contact spring with bending extension block further, and described movable contact spring through hole is opened on arc-shaped transition block.Adopt above-mentioned setting, the structure of movable contact spring can be made more reasonable.
