In the second embodiment, the principle that the trigger ram 3 controls the micro switch 1 to be turned on or off is specifically as follows:
in the process of relative sliding, the trigger pressing head 3 slides to the first abutting body 222 through the connecting plate 221a along the X-axis direction, and the first abutting body 222a abuts against the switch elastic sheet 11, so that the switch elastic sheet 11 moves downward along the Z-axis direction to drive the switch elastic sheet 11 to press the switch button 12 until the micro switch 1 is turned on.
In the whole relative sliding motion process, the switch elastic sheet 11 is deformed under the protection of the protection elastic sheet 2, the trigger pressure head 3 cannot be in direct contact with the switch elastic sheet 11, the risk of circuit disconnection caused by damage of the switch elastic sheet 11 is avoided, the use reliability of the micro-switch assembly is improved, and therefore the reliability of a micro-switch system applying the micro-switch assembly is high.
Further, the first abutting body 222a is arranged in parallel with the switch elastic sheet 11, and the arrangement enables the first abutting body 222a to abut against the switch elastic sheet 11, so that the first abutting body and the switch elastic sheet are in surface contact, the contact area is ensured to be large enough, and the pressure intensity of the contact surface is reduced, thereby preventing the switch elastic sheet 11 from being damaged due to overlarge pressure stress, and further improving the reliability of the micro-switch assembly.
