Nintendo Patents Watch

On the same day that the GameCube Controller’s wireless certificate was updated in Japan, Nintendo also filed to update the certificates (imgs below) for the Switch 2 console, Joy-Con 2, and Pro Controller 2 in Taiwan, adding a new manufacturer—Foxconn EV Energy & Component in Vietnam. This is the second Foxconn Group subsidiary (Foxconn Technology Co. is the first) and the second Vietnamese factory (Hosiden is the first) for Switch assembly.

Some 2024 reports indicated that the site would produce Switch 1 and its accessories from 2027. Since then, the only reports and hiring ads for the site that I could find only mentioned manufacturing of EV parts (hence the subsidiary name), monitors, and printers. So the new regulatory filing shows that the plan is moving forward, and has been upgraded to producing the Switch 2 system. It’s reassuring that Nintendo is further diversifying the supply chain.

Here is the list of Switch 2 system assemblers according to the revised NCC filing:

• Hong Fu Jin, China (Foxconn Technology Co. subsidiary; FTC itself a Foxconn Group subsidiary) → Switch 2, Joy-Con 2, Pro Con 2
• Qingdao Mitsumi, China (MinebeaMitsumi subsidiary) → Joy-Con 2, Pro Con 2
• Zhuhai Mitsumi, China (MinebeaMitsumi subsidiary) → Switch 2
• Hosiden Vietnam, Vietnam (Hosiden subsidiary) → Switch 2, Joy-Con 2
• Foxconn EV Energy & Component, Vietnam (Foxconn Group subsidiary) → Switch 2, Joy-Con 2, Pro Con 2
• Minebea, Cambodia, AMM Division (MinebeaMitsumi subsidiary) → Pro Con 2
• Minebea, Cambodia, SYS-O Division (MinebeaMitsumi subsidiary) → Switch 2, Joy-Con 2, Pro Con 2

Notes:

• All listed assemblers may or may not manufacture all listed products simultaneously.
