When the locking section 62 is locked in the recess 521, the switch connector 100 is locked, and the return spring 7 is compressed by the button 2; when the locking section 62 is disengaged from the recess 521 and enters the guide groove 51, the return spring 7 pushes the button 2 away from the base 1 by its own elastic force, and the switch connector 100 is unlocked.
Meanwhile, when the locking push rod 6 is located at the unlocking side of the guide groove 51, the key switch 100 is unlocked, and the stationary contact 31 of the normally open pin 302 is not in contact with the movable contact 41, and at this time, the circuit where the key switch 100 is located is not turned on. When the locking push rod 6 is located at the locking side, the key switch 100 is locked, and the fixed contact 31 of the normally open pin 302 is contacted with the movable contact 41, at this time, the circuit where the key switch 100 is located is conducted.
In the present invention, before the switch connector 100 is assembled and molded, the locking member 5 is integrally injection molded with the base 1, and the locking member 5 is located below the bottom of the base 1, that is, the locking member 5 and the base 1 have the same tolerance, so that the locking member 5 can be stably assembled on the base 1, so as to ensure smooth pressing of the switch connector 100 and good movement of the locking push rod 6 in the guide groove 51. At the same time, the projection 14 of the base 1 is held in a retaining manner in the recess 54 of the locking element 5, so that the locking element 5 has a sufficient holding force for fixing in the base 1 when the locking plunger 6 slides in the guide groove 51. And, the outer wall of button 2 and the inner wall of base 1 all have the clearance in vertical and horizontal, and the width of vertical clearance is 0.2 ~ 0.4mm, the width of horizontal clearance is 0.3 ~ 0.5mm, and above-mentioned clearance width has guaranteed that button 2 does not have obvious rocking when being pressed.
It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific examples of implementing the invention, and that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
