Is there a way to force the state of on/off switch in 3-D world?

In normal worlds, I can force a on/off state with a simple contraption like so:

----||SP|
|OF|SH|

SP = sideways spring OF = On/Off switch SH = Shell with the color of the block I want to force on the square

This contraption works by immediately killing off the shell if the color I want is active, and triggering the on/off block then killing off the shell if its not.

Unfortunately, I can't do this in 3D world because red/blue switchable blocks do not exist, so is there another way to force the on/off state with a contraption?

I need to be able to specifically set it to on/off, not just a toggle.

Solution 1:

Based off of the answer by l I, you have a few options. Since on/off switches only interact with a couple of things including conveyor belts, the designs for this are going to be based off those, naturally.

Option 1: Activates instantly, but may be faulty from spawn order.

Option 2: Does not activate instantly, but has a simple design and is very small. It will still work regardless of snow theme or not.

Both designs are pretty compact, but option 2 also requires 1 less entity.
