Reply to Foot switch for S4

Hi Guys.

There's thread to buy BOSS FS-5U. But I'm just wondering can we use these cheap footswitch for S4?

"Tattoo Foot Pedal Switch For Tattoo Power Supply Kits" (http://cgi.ebay.com/Tattoo-Foot-Peda...#ht_2071wt_956)

Its less than 10 bucks and it should do the job right? Please help.

Thanks
