Description

Sensitive switch

Technical field

The utility model relates to a kind of sensitive switch as the electrical equipment interior fittings.

Background technology

The sensitive switch of Xiao Shouing generally comprises shell in the market, have switch on the shell, also comprise operation strip in the shell, binding post, support, reed and lever, support is fixing in the enclosure, one end rotational support of lever is on support, operation strip is enclosed within on the support and is horizontally set in the shell, the other end and the operation strip of lever cross, one end of reed is connected with support, the other end is connected with operation strip, when being pressed down, switch can promote lever and operation strip simultaneously, operation strip is pushed the convertible and different binding posts in back and connects, switch of this sensitive switch is subjected to move in shell after the pressed by external force, and promotion operation strip, when external force is withdrawn, because operation strip is resetted by the reed effect, and drive switch resets at once, therefore the control element that is equipped with in the electrical equipment when this sensitive switch is installed on each electric appliances inside must be able to continue to split the conversion that the climax application of force can be finished circuit connecting relation, increase the manufacture difficulty of electrical equipment, also limited the scope of application of sensitive switch simultaneously.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of sensitive switch, and switch of this sensitive switch resets in the position that is subjected to can being positioned when external force is once pushed finishing the conversion of sensitive switch circuit connecting relation and being subjected to finishing when pushing once more.

For this reason, the sensitive switch that the utility model provides comprises shell, have switch on the shell, switch is equipped with and can impels it to finish the position of sensitive switch circuit connecting relation conversion and be subjected to finishing the locking mechanism that resets when pushing once more being subjected to can being positioned when once pushing.

Because being equipped with, switch of the sensitive switch that provides of the utility model can impel it can be positioned when once pushing to finish the position of sensitive switch circuit connecting relation conversion and be subjected to finishing the locking mechanism that resets when pushing once more being subjected to, switch of sensitive switch can move down and be subjected to the locking mechanism locking when switch is subjected to pressed by external force, switch is positioned to finish the position of sensitive switch circuit connecting relation conversion, therefore the sensitive switch that provides of the utility model is installed on the control element that electrical equipment is equipped with in the electrical equipment when inner and needn't continues to split the conversion that the climax application of force can be finished the sensitive switch circuit connecting relation, and only need split the of short duration external force that applies of climax, the circuit connecting relation that is kept when sensitive switch also can keep splitting the climax application of force when external force is withdrawn.In sum, the sensitive switch that being equipped with the utility model provides can reduce the manufacture difficulty of electrical equipment internal control element, and can enlarge the scope of application of sensitive switch, makes the parts that can't continue the application of force in the electrical equipment originally also can be equipped with sensitive switch.
