Ball locks!, you obviously are not working in the field
we repair pcbs, thats what we do
and so when one of your colleagues tells you a semi conductor relay is "short circuited" you will pursume he means what exactly?
to have GONE short circuit would be a faulty relay
Semiconductor relays are basically optocouplers where a short circuit on the output would be a fault condition
it doesn't change the definition of short circuit. for example, if you measure the resistance of a piece of (normal) wire, you would expect to see a short circuit between the two ends. You would also say that there is continuity between the ends, but that doesn't detract from the fact that it is a short circuit and, believe it or not, NOT a fault condition
and a circuit through a switch will be viewed as a closed circuit condition not a short
no it doesn't, that phrase gives no indication of the health of the connection
and the phrase "short circuit" gives what indication of the health of the connection exactly?
no indication whatsoever other than that there is no resistance between the two points
I certainly wouldn't want someone with your incomplete understanding anywhere near any appliance of mine
I'll not sleep now, worrying about your opinion
sleep indicates active brain function, steady on there
