peer agreement (net): +3My guess Explanation: I would assume here that the difference is between, say, optoelectronic contacts and real metal-to-metal relay contacts. The optoelectonic contacts have a photodiode that emits light when current passes through it. This light is sensed by a phototransistor that conducts when it senses light. While these devices are encased in the same block of plastic there is NO physical, electrical connection. So in my opinion, this is NOT a "hard contact" in your sense. Relays, on the other hand, have metal that contacts metal to send the electrical current on its way. This, then, would be your hard contact. My thoughts from the USA. |
