I found some spare switches at Sweet-vapes.com. Sent them an e-mail but couldn't give me a straight answer or not. I asked them if their 18650 switches would fit the model I am getting. I know that there is a newer and older model of the 18650 and I am getting the older model. Will the newer model 18650 switches fit the older one, if not, where can I buy these at? I know the button would stick on the older model that's why they upgraded it. They told me just to buy one and see if it fits, but I don't have 15 bucks to just throw away as I am poor..lol So if anyone knows where to get spare switches at if these don't fit, PLEASE let me know. Thanks.
