From http://www.scescape.net/~woods/elements/ruthenium.html
"The metal is one of the most effective hardeners for platinum and palladium, and is alloyed with these metals to make electrical contacts for severe wear resistance." The extreme hardness of these contacts means that since perfect flatness cannot be achieved in relay contacts, such contact is limted to a discrete number of points. Would anyone care to guess how many points of contact can exist between two nonflat surfaces that are not soft enough to conform? Obviously, between surfaces separated by nanometers, conductivity can also occur. Would anyone care to characterize this as well? |

How hard is extreme hardness? Ever occur to you the harder the contact the smoother it can be polished? Which factor takes precedence in determining contact resistance, smoothness or malleability? Would anyone care to guess how many points of contact can exist between two nonflat surfaces that are not soft enough to conform? What happens if a very hard but microthin plating is applied to a flexible base metal contact? Will it conform to form multiple contact points? Obviously, between surfaces separated by nanometers, conductivity can also occur. Would anyone care to characterize this as well? You're reminding me of Trots claiming cable insulators acting as dielectrics are an audible factor. What was it you were pursuing a PhD in? ScottW |

Irrelevant to the relay contacts used in the ABX RM2 comparator, because those contacts are not solid ruthenium. Instead, the ruthenium is a thin plated layer desposited over softer copper contacts. Since the question is irrelevant, there is no logical purpose in answering it. Besides, its rhetorical. That would make two good reasons not to answer it. |

Obviously, between surfaces separated by nanometers, conductivity can also occur. Would anyone care to characterize this as well? (Parasitical) capacitance, in parallel with the surface resistance. Usually negligible. I have found entire papers on the physics of the contacts that show the problem is far more complex. To give an example of something easier to grasp, consider lubrication oil. It turns out that lube oil in bearings oxidizes. In bearings with large clearances, the effect is negligible. In bearings with small clearances, this accelerates death of the bearing. There seems to be an assumption that because audio is low frequency, and because it's been around for a long time, and because it can be realized without microelectronics, that audio is far removed from quantum effects. But you, as a tube user, know this to be false, because when you turn up the gain, you hear shot noise, which is a quantum effect. Likewise, it turns out that the physics of contacts involves both quantum effects and something else. The contact pairs have the characteristics of an unintentional nanomachine. At this scale, mechanical and electrical characteristics become intertwined. Remember that line level audio, at the zero crossing, involves nanoamps and microvolts. In order to introduce the subject, I asked the question, "For two hard, imperfectly flat surfaces, what are the maximum number of contact points?" The purpose was to invite some discovery on the part of the readers of this newsgroup. |

It is very important, because the actual surface area that is in physical contact is extremely small. This makes the bulk conductivity of ruthenium important. Quantify the contact area and demonstrate through specs that ruthenium contacts have significantly greater resistance than relays of comparable size contacts. I look forward to you providing more than just idle speculation from your extremely poorly thought out and fundamentally flawed theories. ScottW Answer the question, Scott: Two hard and nonparallel surfaces can have a maximum of how many contact points? Why are you changing the question, Bob? Anyway, it still depends on their shape.....and we're not talking diamond hard here so your inference that there is no conformance is just hogwash. ScottW |

I have found entire papers on the physics of the contacts that show the problem is far more complex. I am aware of some aspects of those physics. Generally, in at least line level audio signals, driven from a low output impedance, those problems are negligible, providing the right relay or switch is chosen for the application. For line levels, for me, nothing else comes into consideration but thoroughly gold-plated, gas filled relays. For speaker-level signals, a combination of both silver-plated and gold-plated heavy duty contacts with strong spring action (meaning contact pressure) are a good choice (if one has to switch speaker-level signals at all, something I don't like to do at all). Switching an audio signal at microphone- or phono cartridge levels is almost not possible without suffering from signal degradation. To give an example of something easier to grasp, consider lubrication oil. It turns out that lube oil in bearings oxidizes. In bearings with large clearances, the effect is negligible. In bearings with small clearances, this accelerates death of the bearing. I'm not sure if this is comparable to relay switch action. There seems to be an assumption that because audio is low frequency, and because it's been around for a long time, and because it can be realized without microelectronics, that audio is far removed from quantum effects. But you, as a tube user, know this to be false, because when you turn up the gain, you hear shot noise, which is a quantum effect. Correct, but what's the correlation between shot noise and relay contacts, else than possibly involved quantum mech effects? Likewise, it turns out that the physics of contacts involves both quantum effects and something else. The contact pairs have the characteristics of an unintentional nanomachine. At this scale, mechanical and electrical characteristics become intertwined. Remember that line level audio, at the zero crossing, involves nanoamps and microvolts. Also correct, that's why selecting the right relay for the job is so important. I've measured signal drops of 3 dB with badly chosen relays (IMHO), in a circuit with impedances involved of about 50 kohms. That was in a highly touted high end product (a preamp), the type of which I won't reveal as to not disappoint readers in posession of said preamp :-) In order to introduce the subject, I asked the question, "For two hard, imperfectly flat surfaces, what are the maximum number of contact points?" The purpose was to invite some discovery on the part of the readers of this newsgroup. I said 3 contact points, 3 points being the most stable way to put two surfaces together (think about a table with 3 legs). Applying more contact pressure won't change that :-) -- "Audio as a serious hobby is going down the tubes." - Howard Ferstler, 25/4/2005 |

This is quite reasonable. It is only when a gadget is supposed to be used to establish a reference point that it has to come under exquisite scrutiny. In that case, one has to turn the problem over and over, examining all the literature. Switching an audio signal at microphone- or phono cartridge levels is almost not possible without suffering from signal degradation. To give an example of something easier to grasp, consider lubrication oil. It turns out that lube oil in bearings oxidizes. In bearings with large clearances, the effect is negligible. In bearings with small clearances, this accelerates death of the bearing. I'm not sure if this is comparable to relay switch action. It is not. I gave it as an example of a scale-related problem that may not be useful to everyone. There seems to be an assumption that because audio is low frequency, and because it's been around for a long time, and because it can be realized without microelectronics, that audio is far removed from quantum effects. But you, as a tube user, know this to be false, because when you turn up the gain, you hear shot noise, which is a quantum effect. Correct, but what's the correlation between shot noise and relay contacts, else than possibly involved quantum mech effects? It is supposed to make people think about assumptions. It is not integral. The mechanical junction is made out of paths that have been denoted "nanowires". Current through nanowires follows quantum steps. And then there is the nano machine effect; at this scale, mechanical rearrangement occurs with variations in the current/potential. Likewise, it turns out that the physics of contacts involves both quantum effects and something else. The contact pairs have the characteristics of an unintentional nanomachine. At this scale, mechanical and electrical characteristics become intertwined. Remember that line level audio, at the zero crossing, involves nanoamps and microvolts.
