Servo Motor Driver Matt Zwarts

thingiverse

This is a quick design I made to mount a 9 gram servo between 2 limit switches, the purpose of it is to allow triggering a DC motor to power left and right, with only the servo driven from an RC transmitter. It means there is no need for a motor driver required from the RC transmitter, it acts like a large relay switch, a bit more simple to use. See the images for how I used it with 2 limit switches on a pericope lift mechanism, and wiring schematic I based it on. Search online for a Youtube video on how to make it work, it's hard to describe it all here. There are 2 versions for different sized switches, print one and see if it fits your switches, the switch I ended up using was for the small version. Here are the ones I used and the servo is only a 9 gram servo: https://www.banggood.com/10Pcs-Micro-Limit-Switch-Roller-Lever-5A-125V-Open-Close-Switch-p-945733.html?rmmds=myorder https://www.banggood.com/TowerPro-SG90-Mini-Gear-Micro-Servo-9g-For-RC-Airplane-Helicopter-p-1009914.html?rmmds=search&cur_warehouse=AU Happy Building!
