Description
Technical field
It the utility model is related to a kind of trigger mechanism of switch, more particularly to a kind of double elasticity triggerings for microswitch
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.
