The Shuriken Korean Lever PCB will come without the switches installed. The main part that keeps the PCB in place are the screws that are installed on a lever to secure the switches. Follow the steps below for installation procedure. The below installation examples are with a Taeyoung Fanta Lever.
1. Unscrew all switches and remove from the lever body

2. Install switches onto Shuriken Korean Lever PCB. Switch can enter the clip from above or from the side. Make sure it is fully inserted and the holes on the PCB can be seen through the holes of the switch.

3. Place Shuriken Korean Lever PCB onto the lever housing, carefully aligning the pegs through the switch holes. Then re-install all screws.

4. Plug in the 5-pin wiring harness into the pin headed

5. Installation is complete and ready to use!
In the case of 0.187in switches, it is advisable to use a needle nose plier to slightly bend the terminals forward for better contact. This can be demonstrated as below.
For 0.250in switches, no bending is necessary. When changing 0.250in switches to 0.187in switches, it is advisable to pinch the terminal close to allow for a better electrical connection.

The Shuriken Korean Lever PCB was specifically designed for the Gersung GSM-V series and Omron V, D2RV, & D3V series switches. The PCB also fits a wide range of levers. See list below along with installation notes.

ASI Golden Lever |
Requires shorter M4 bolts because default bolts will hit the plate as they are too long. M4X25 or M4X30 have been reported to work as a replacement. Also note that variable switch spacing feature will no longer work. |

Cool Bear Lever V1 |
Stock M3 bolts holding down the switches are too short by 2mm. Requires purchase of 8 x M3 x14mm bolts |
