Abstract
A scissors-like linkage structure for use in a key switch includes a first arm having a pivot and a second arm. The second arm has a slot with a first portion and a second portion. The first portion is larger in diameter than the second portion. The pivot selectively moves to the first portion and the second portion. When the pivot moves to the second portion to engage with the second portion, the first arm is rotatably connected to the second arm in a connection configuration. When the pivot moves to the first portion, the first arm and the second arm are in a semi-connection configuration. A method for assembling the scissors-like linkage structure includes the step of forming the scissors-like linkage structure to position the pivot in the first portion of the slot in one injection mode. Then, the pivot moves to the second portion of the slot to engage with a wall of the second portion of the slot.
