Mini Mouse Wheel Scroll Encoder Switch

SMT MINI mouse encoder switch

Working Principle

Mouse scroll wheel drive encoder brake wheel to rotate 360°,brake wheel derives the reed claws and base terminal contacted to produce ON-OFF electrical property,A-C terminal input 12 pulse signal,B-c terminal outputs 12 pulse signal,mouse IC chip discerns the sequence ofA-C&B-C pulse signal to distinguish the wheel positive rotation or reversed rotation.

The time difference of A-C and B-C terminal pulse signal was called phase difference.the mouse scroll rotates a circle will have 24 phase difference,After the mouse IC chip reading thbe phase difference,it will give out rotation signal
