This is a simple foot pedal switch to activate a small drill for making the holes on a pcb.
Most mini drills have a switch in their body activated by hand which is ok for most applications.
When drilling pcb though, the constant on-off needed for the holes to be drilled accurate and with minimum damage to the cooper this can became tiring to the hand, so the purpose of a foot activated switch emerges. Although this is made with pcb drilling in mind it is not obligatory to have this only use, afterall is a foot activated switch waiting for you to find more uses for it.

The materials needed are common and easily obtained through local stores in cheap prices.
We had some spare acrylic glass so we used that but you can also use wood, aluminum or any other material you can find with ease and suits you.
To start you need a mini drill along with its power supply.
A switch to activate the drill, one from guitar pedals would be perfect but anything else with a strong spring to hold the upper plate and give a feeling to your feet is ok.
Two plates of 10mm acrylic glass 21cm long and wide enough to feel comfortable with your foot size.
4 smaller pieces to make some casing for the switch and allow cables to pass through, dimensions here are not crucial, any spares or leftovers will do.
A couple of hinges to connect the 2 plates, some M3 screws to mount them and some longer M4 to mount the switch assembly to the plate.
If you go with acrylic glass for the switch assembly, some glue for it will give a better aesthetics instead of using screws but it's up to you.

tell me. It is not helpful to use one kind of spring or its enough with the switch?
You have to push twice to go On and Off?
Do you think that it is hard to do one which you can control the amount of power from the switch , so you can control the revolutions on your drill??
It depends on the switch you use, if it is from a guitar pedal for example no need for extra sping, if switch sping is to soft you can add another one harder.
It is one push on one push off.
You can add a potensiometer to have a proportional speed control but it would be a bit more complex.
