Hoping someone can help with this small little project. I reload ammo and I want to make what is known as a "vibrating powder trickler", basically a funnel that fits into a hole in a small aluminum block (roughly 3/4"x3/4"x2"). The end of the block has a hole that meets the vertical hole where the funnel mounts. A long 1/4" aluminum tube fits into the end hole. Under the bottom of the aluminum block a small cellphone vibrating motor is attached. The block is a vertical hole on the back side that slides over a wire mounted in a weighted base and a thumv screw allows you to raise and lower it. The device is also mounted at a slight angle so the powder will trickle down the tubne under vibration. The idea is to pour powder in the funnel, then using an intermittent switch, the cellphone vibrating motor causes the powder kernels to vibrate down the tube and into the weighing pan. It is typically powered by a pair of AA batteries. To make the device more effective, two switches are used. One switch draws power only from one battery to get 1.5v, the second switch will draw power from both batteries for 3v so you have a "slow" speed for trickling individual kernels of powder at a time and a "fast" speed so you can trickle more volume quickly to get to your target weight sooner.
The two little buttons (sourced from Amazon) each have two poles for attaching the wires. The batteries are housed in one of those little project battery holder/pack things. The vibrating motor is also two wires. How would I attach the wiring to the two switches and the battery pack so one button uses power from just one battery and the other button draws power from both?
