Wiring Information: This arcade button requires 2.8mm crimped wires for connection. 1 wire for ground connection (CO) and 1 wire for signal connection (NO). Pre-crimped 2.8mm wires and 2.8mm daisy chain ground harness can be ordered here: Wires & Cables
These have the microswitches built in and do not appear to be as solid as ones with separate microswitches, but only time will tell. Be aware that as stated these use 2.8mm terminals, but most wiring uses 4.8mm crimps (e.g. Jamma wiring harness), so 4.8mm will not fit great. Spend a little more and get better switches.
