Hello all.
I want to start off by saying that I am a very beginner level hobbyist.
I am looking to hook up 3 linear actuators (or something similar) in a simple toggle switch circuit. I do not need to control the actuator speed, so no control boards are desired. The simpler the better. Just a simple on and off, most likely using a DPDT switch.
The goal is to lift (push) a metal tray with a sample that weighs 50 grams in the air so that it is above a precision balance. I want to weigh the tray and sample but it will be inside an environmental chamber so i can't open the door which is the reason for using an linear actuator or something similar. After weighing, i would like to lift the tray back in the air so the balance is at 0 g.
Limitations/requirements:
I was looking at two types of linear actuators

and
No laughing, but i was looking at the LEGO linear actuator. they are hard to find, but still out there.
due to low duty cycle and lifting such a small mass, maybe this can work

Can this be done? If so, could you please direct me how this sort of thing is wired or any other useful information.
thanks for your time

Limitations/requirements:
- My total height cannot be more than 4" which includes the extension.
- Currently, I have 2 wires available to me that passes from the outside to the inside of the chamber. I can make more openings but only if i have not other choice. It is a real pain in the butt to do.
- 3 actuators will have to work in parallel. Exact timing is not critical as i believe there is a small amount of room for error, but it should be pretty close so that an object can be lifted.
- Duty cycle is not important. It may be cycled ~100 times in ~2 months. that is about it.
