Bike Handlebar Button (BoosterPack Throttle)

This is intended as an accessory for the Bicycle BoosterPack (Project seen here: http://bit.ly/28XhHxg).
Originally I recommended buying a handlebar button assembly from Amazon but they have since tripled their price to ~$18. This model will enable you to get the same functionality for the price of the switch & a screw ~$5.

There are two different sizes provided depending on where you want to mount it. See image for standard bar sizes. Most folks will need the .875" diameter size as I did
