You may remember that in another post i commented that i had a FOC replacement for the failed Ultimate speed charger. Dismantled the old one today and the cause of the failure was the cheap DPST/PTM switch, pity such nice electronics let down by a 10p switch. Works fine now, and i have two for the price of one :)
Nice one. Always good to have more than one.
Nice one. Do you have a part number etc for the switch replacement - there seem to be thousands of variations.
It?s a 6x6mm Momentary SPST (not DP as i originally said) like this
Replacing the miniature push button with a spare one from a toaster fixed the problem. I was also suspecting the button at first but I thought it would be too straightforward.
Thanks!
Nice to see there is a fix! Just one question,appart from being "SPST", the switch is normally open or normally closed?
I'm betting on it being a normally open contact (but no absolute certainty so a good question). Most push button spst switches are of the NOC type since the most common applications utilise a "completion of circuit" detection methodolgy (e.g 'Bell Push', 'pull down' for cmos/ttl electronica and so on).
Yes, there can be contrary requirements for NCC types but these are mercifully few and far between, usually in specialist kit, often using custom push button switch assemblies.
Of course, if you're planning on buying a replacement switch, you can cover both eventualities by buying a change-over DPST push button switch and wire the appropriate contacts according to the circuit requirements.
They are a 6x6mm- with 4mm button normally open switch like this
