Here's more thoughts, regarding HOW TO shut off a (rotary signal) switch, when the energy for doing that is supplied by...(You guessed it); supplied by, or sourced, by the double-pole switch itself. Imagine the moving toggle; when the toggle, in standard electric switch leaves the 'pole' contact, that energy is stopped, and same thing occurs with mechanical commutator switches; that is, the source that causes switch movement, in the first place, is no longer there. A small flywheel, perhaps, or some kind of spring, could maintain power, as it winds down; pushing the switch to complete arc of travel. By using split paths, the arrangement can maintain power, in a portion, (actually literally in the next station), and the 'turning off', or de-selection, can occur, crossways, from right side, over to go transparent mode on left side portion. The right side, in current station, has been put into transparent mode, already, and with the actual right side 'active' state actually being in the following station (confusing!). That is a situation where the 'active' status is 'smeared' a little, across a couple of stations simultaneously. A FLYWHEEL ?? Man, this sh~π's getting out of hand (lol)...What's next: ...I can't even think of anything, that this design process can't top... How about: Requirement for a FLAGMAN and two flares, for warning folks: "Warning, Mechanical Switch." ... At any rate, like I said, these are interesting questions, I want to know, and PLUS, besides, there could be other projects that come up, for experimenting with Mechanical Logic options. |

Some more improvements: Picture shows 'Back Face' panel, make from 'plexiglass' or similar soft-flexible, so that can hold parts aligned and for testing. As with other internal parts, the face plate has no attaching screws etc. Actually, for light weight duties, the little (1/8) wood shafts do well holding the plate steady. Red color portions, are 'A' logical segment, of the 3-part switch box. (Think 3 - Contactor mechanical positioned switch assembly). |

One new part built, is the moveable toggle lever. It has a 'Tip Wheel', driven by belt from pivot area (has same axis). The tip wheel has pulley, while belt driver pulley rests or is supported by the stationary pivot shaft. For each of the 3 switches, the 'chain' input is what drives the pivot mounted, and thus the tip wheel, for selecting 1 of 2. Photo shows pivot lever or 'toggle arm', omitting the tip and drive wheels (in this partial mock-up). |

Arrangement for SET and RESET: In this picture, it helps to view as 'planes', where the wood panel is 'outputs' compartment. So going towards viewer's foreground, the several different planes are shown spread out, for clarity. First, see larger yellow pulley wheel, meant to match with the blue color drive pulley, seen diag down / left. That is 'SET', causing the toggle lever to move. Alternately, logically, the RED color pulley, is meant to match, with the white color wheel, diagonally right nearby. Actual 'data' being switched, or commutated, is, yet another 'plane' compartment; that's the two white colored wheels, at the more 'picture foreground' end. For orientation; the two faces, front and back, resemble a wall clock, where the clock front face is the 'outputs', and back face has some inputs, or even a 'winder'. I like to consider switch box having NORTH-SOUTH axis, from back to front (outputs). Thus, the sides, of the box, are EAST-WEST, orientation. |

PROBLEMS WITH SELF-SWITCHING: The switch box has a combination of generic components and some customized interconnections, (for implementing this particular network). |
