Two-way instant switch
thingiverse
This switch enables bi-directional motor control, suitable for servos or actuators. However, avoid high-voltage applications as it's not designed for 230/115V. It was designed for a water valve actuator powered by four li-ion cells, offering a year or two of use without recharging. The switch is springy; if loose, heat the connector lever's box to 110-120°C before pushing it towards the center. A blocky element is necessary to prevent the knob from melting. Print with 0.5 infill, two perimeters, and a layer height of 0.334. Attach 1.5mm2 copper or silver-coated copper wires to the lever and walls as desired. The attached photos may appear coarse due to low-quality black ABS used.
