Movable contact spring 23 is fixed on groove, under natural conditions, spring plate 23 is reclinate arcuate structure, and both ends are respectively equipped with
First contact 16.The other end of push rod 15 is threaded through in the positioning sleeve of 14 lower end of shell.Second spring is also coated on push rod 15
20, second spring 20 is in compressive state in its natural state, and the upper end of second spring is resisted against on the following table of boss, the second bullet
The lower end of spring 20 is resisted against the top of positioning sleeve.Second spring 20 is in compressive state, and push rod 15 can be made by upward thrust, boss
Upper end be resisted against on the inner wall of shell 14, to prevent microswitch in the case where receiving vibration, about 15 push rod follows vibration,
Lead to the unstable on-off for influencing circuit of contact contact.
It is also equipped with press piece 4 in the upper end of electrode box 5, press piece 4 is obliquely installed, and one end is consolidated 5 upper end side of slot electrode box and inserted
In slot, the other end is folded upward at.Press piece 4 it is upper it is unilateral be in contact with the lower end convex block 6 of button 8, under the unilateral top with push rod 15
Portion is in contact.Button press 8, bending end motion of the convex block of 8 lower end of button to press piece 4.
It is equipped with the second contact 19 being fixed on shell 14 in the lower end of the first contact 16, is set in the upper end of the first contact 16
There is third contact 18.Under natural conditions, the first contact 16 is contacted with the second contact 19, forms normally-closed contact.This switch contact is adopted
It is made of silver-nickel, silver-nickel is widely used environment-friendly materials, has conductivity, thermal conductivity good, is had very high
Ablation resistance, relatively be suitble to control resistive load.Second contact 19 of the present embodiment and third contact 18 are connected to and extend in
Contact chip 17 outside electrode box 5, contact chip 17 are used to access in the circuit that need to be controlled with by this switch.
When the utility model is used, the contact chip of this switch 17 is accessed circuit first, button press 8, button 8 can be around
Articulated shaft rotation, while the first spring 7 in button 8 is compressed, the convex block 6 under button 8 presses the press piece 4 being in contact with it, and presses
Piece 4 pushes push rod 15 to move downward and compress second spring 20, and 23 both ends of movable contact spring on push rod 15 are upward by upward power
Bending, makes the first contact 16 be in contact with third contact 18.After the power of button press 8 disappears, this switch is restored to nature shape again
State.
In order to make the utility model switch seem beautiful, the extension end of the contact chip 17 of the present embodiment switch is arranged in
The lower end of this switch, referring to fig. 2.Switch two sides further respectively have cover board 3, play the role of decoration and fixation.
Movable contact spring 23 is elastic part, is in bending stress for a long time or diversion stress effect is lower repeatedly and bears the work of electric current
With.In the long-term use, if stress relaxation, the contact pressure between contact can be made to reduce, leads to poor contact, therefore dynamic spring
The material of piece 23 must have good elasticity, electric conductivity and mechanical fatigue strength.In this switch designs, according to product structure
And performance requirement, select elastic higher, good toughness and the excellent beryllium-bronze QBe material of electric conductivity.For guarantee switch can
By property, the size of key part movable contact spring 23 must assure that precision, and high-accuracy multiple-die press punch forming is taken to be made.Through overheating
Treated part, can be improved the elasticity, intensity and hardness of part.Movable contact spring 23 after high-accuracy multiple-die press punch forming,
Elastic processing is carried out in vacuum heat treatment furnace, and then meets the requirement of intensity and elasticity, guarantees that the performance in 15000 service life refers to
Mark.
