This article covers エンドゲームギア(Endgame Gear) OP1we スイッチパック Kailh GO 60-65gf スイッチPCB 2個セット プラスドライバー 付属 EGG-SP-KGO-606.
Overview
The Endgame Gear OP1we Switch Pack (model EGG-SP-KGO-606) is a dedicated replacement switch PCB kit for the OP1we gaming mouse. It includes two Kailh GO 60-65gf switch PCBs, a PH000 screwdriver, and a quick-start guide, allowing users to change the click feel or replace worn switches on their own. Unlike the stock switches found on the standard OP1we, these Kailh GO switches offer a heavier actuation force of 60–65gf. This reduces accidental clicks and provides a more deliberate, tactile feedback—ideal for competitive gamers who demand precision. The kit is available through Japan and other retailers.
Connectivity & Compatibility
This switch pack is exclusively compatible with the Endgame Gear OP1we mice in both black (EGG-OP1WE-BLK) and white (EGG-OP1WE-WHT). It will not work with any other mouse model. The replacement process involves unscrewing the bottom plate, carefully swapping the switch PCB, and reassembling. A PH000 screwdriver is included. Caution: mishandling internal components or the switch itself voids the warranty. No software or driver configuration is needed; the modification is purely mechanical. Users should follow the quick-start guide precisely to avoid damage.
Product Info
Released in late 2023, the OP1we Switch Pack typically retails for around ¥2,000, but as of June 2026 the street price on Japan is approximately ¥5,155. The warranty covers only initial defects, which is standard for such accessory parts. Kailh GO switches are known for their durability and consistent feel over millions of clicks. Included in the box: two Kailh GO 60-65gf switch PCBs, one PH000 Phillips screwdriver, and a quick-start guide. Market positioning: this is a niche replacement part for high-end gaming mouse owners who want to customize or maintain their OP1we without buying a new mouse. Being an official Endgame Gear accessory, compatibility and build quality are guaranteed.
Best Use Cases
Competitive FPS players: Heavier switches prevent accidental shots during intense moments, improving accuracy. The 60-65gf force provides a confident, crisp click. Long-term OP1we owners: If the original switches have degraded after heavy use, this kit rejuvenates the mouse at a fraction of the cost of a replacement. * Customization enthusiasts: Gamers who enjoy fine-tuning their peripherals will appreciate the different tactile character of Kailh GO switches compared to standard options. This product is not recommended for anyone who does not own an OP1we, or for those seeking a universal switch replacement—it is strictly tied to that specific mouse model.
