Genuine Korean Gersung microswitch for Crown / Samducksa Korean arcade levers. This is the standard-hinge A3 switch and uses 4.8 mm (.187") connections.

Confirmed compatibility

• Crazy Dongpal (original CWL-303MJ-DX): uses 4 × GSM-V1623A3 switches.
• Crown / Samducksa 303, 307 and standard 309 series: commonly uses GSM-V1623A3.
• Knee Lever Neo: used as the single standard-hinge switch in the 3-wide-hinge + 1-standard-hinge configuration. On the Knee Neo unit inspected by Arcade Forge, this GSM-V1623A3 was fitted in the UP (U) position.

Best for

Replacing a worn, inconsistent or faulty standard A3 directional switch without changing the original lever geometry. Particularly useful as a spare for the original Crazy Dongpal and for the standard-hinge position on Knee Neo.

Important: Knee Neo also uses wide-hinge switches on the other directions. Do not automatically substitute this standard-hinge version for a wide-hinge KN/HM/DP switch. Check the model printed on your existing switch before ordering.
