Description
Technical field
A kind of trigger mechanism of switch is the utility model is related to, more particularly to a kind of dual spring for microswitch triggers
Mechanism.
Background technology
Microswitch is that have small contact separation and snap-action mechanism, and it is dynamic to carry out switch with defined stroke and defined power
The contact mechanism of work, is covered with shell, there is a kind of switch of frizzen outside it, because the contact spacing of its switch is smaller,
Therefore named microswitch.Outer mechanical force is acted on power on action reed by actuated element (push-piece, button, lever, roller etc.),
Produce snap action when acting reed and being displaced to critical point, make the movable contact of action reed end and fixed contact quick-make or
Disconnect.After the active force on actuated element is removed, action reed produces counteragent power, when actuated element reverse stroke reaches
After the action critical point of reed, counteragent is instantaneously completed.The contact spacing of microswitch is small, actuating length is short, by power it is small,
Break-make is rapid.The responsiveness of its movable contact is unrelated with actuated element responsiveness.
Traditional microswitch includes housing, panel, normally opened connector, normally closed connector, public connector and normally opened
The dynamic slide plate switched between patch piece and normally closed connector, the single shell fragment or Single spring of dynamic slide plate action are driven, at present on the market
The microswitch used can not meet many Industry code requirements because the limitation of its own structure has many defects, it is impossible to
The higher occasion of safety coefficient requirement or field use, and Market breadth is low.The defects of specific it is following some：
(1) elastic force is produced by the deformation of metal list shell fragment or Single spring tension and realizes switch switching, it is critical in switch saltus step
Position, can exist contact from it is normally closed be switched to it is normally opened during balance occurs, it is normally opened or normally closed so as to cause switch to exist
Loose contact causes switching signal scintillation occur between connector all no powers or sound contact, causes equipment not make
With, such as domestic ice maker etc.；
(2) microswitch physical dimension itself is small, causes conductive metal sheet sectional area small, can not bear larger current,
The use occasion of larger current is needed to be easy for burning, such as the gardens electric tool equipped with lithium battery.
It would therefore be highly desirable to solve the above problems.
Utility model content
Purpose of utility model：The purpose of this utility model, which is to provide one kind, can solve to switch handoff procedure because there is dynamic balance
