Hello guys i'm GTRunner.I have nothing to do in summer so I started to work on redstone more because I forgot the working logic.So after re-learning redstone,I made a BUD Switch for farms.It is capable of 2 slots.Hope you guys like it :).

Features:
~2 slots for seeds (normal switches had 1)
~Only 2 block high (can fit in nearly all houses)
~Currently,the easiest BUD Switch
~MOST COMPACT REDSTONE BUD SWITCH!!!!!!!!!!!!!

Size:

2 block high x 6 block long x 6 block wide(see comments,I completed the challenge)

UPDATE :

This updated version have a very new system,So this might be better than the old one.Challenge completed (see comments)

Additional Notes

Doesn't have a redstone alarm system.But you can add a timeline for de-activating pistons.I will do a tutorial on this after this day(too tired because of soccer matches)
