🔗 Buying the correct buttons from Sanwa official store

If you are buying buttons from Sanwa's official store, it may be confusing as there are multiple listings for buttons.

Product pages are separated by the switch it uses: 1F, DF, or lamp holder (旧型). Before adding to cart, three options will need to be selected: button color, switch, and lamp type. The lamp options are LEDs (5V, 12V, or 24V with colors) incandescent wedge ball lamps (194), or no lamps (LN); LEDs will be an extra charge, while no lamps will have a slight discount.

If you are buying buttons for an HD pop'n music cabinet (Type E or F), click here. These include a Sanwa OBSA-LHS1F-LN microswitch with each button. If you need lamps, select 12V LEDs in your needed color.

If you are buying buttons for an SD pop'n music cabinet, click here. These include a traditional lamp holder and Omron V-10-1A5 microswitch with each button. If you need lamps, select 194 bulbs.
