Editing Tai-Hao APC series (section)

==Description==
APC switches have the same approximate shell design as other [[four-tab clone]] switches. Internally they are very similar to other Alps clone switches, with the current generation of switches using the same narrow copper-based click leaf.

According to Tai-Hao, the APC series was introduced a year or two after [[Tai-Hao Aruz]],<ref>Conversation with Tai-Hao</ref> which has a confirmed sighting of 1989. It was previously misunderstood that the APC series was introduced in 1984 or 1985, but 1990 or 1991 is consistent with the apparent appearance of Alps clone switches around this time.

The contact design of APC is derived from that of the Aruz switch. It remains uncertain whether [[Hua-Jie AK series]] or Tai-Hao APC series arrived first; it is however confirmed that Himake were involved with the Aruz switch, and both switch series started out extremely similar.
