Instructions

I STRONGLY DO NOT RECOMMEND TO USE THIS SWITCH IN HIGH-VOLTAGE APPLICATIONS!
Let's say the upper voltage is 48V. There is no insulation or agreements to work under 230/115V.

I have designed the switch to drive water valve. The actuator, used in central car-locks opens or closes the valve. It is powered from 4 li-ion cells. The cell's charge lasts for a year or two without need to recharge.

The switch is springy, if it is too loose, you may push the thinner part of connector lever's box towards center by warming a little before (110-120 C)

The blocky element is to fine print the knob of switch. Without this it melts and looks ugly.

The print strength is not important, I suggest to print it with 0.5 infill, two perimeters and 0.334 layer height.

Afterwards just put the copper or silver-coated copper wire 1.5 mm2 connectors to lever and to the walls of the working lever, bend it to desired position and use it!

The print attached photos look coarse, but the black ABS I have got is somehow low-quality (too much of poliethylene?). The other colours I use are far better/smooth.
