From: Joerg on 24 Nov 2009 20:48 Hello Folks, Never needed this before but now I do: What are those things called that you unplug and insert 180 degrees rotated to switch the primaries of a transformer between 115V operation (parallel) and 230V operation (series)? Circuit board mount. Or better yet, does anyone know a source? Must be super cheap, as in <<50c altogether in qties, as usual :-) Under categories such as "voltage selector" I only found fuse holders with this feature in there, really expensive plus way too large. I want to avoid a slide switch because someone could accidentally hit it and .... *PHUT* -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.

The classic term used in Marshall and other Audio Amps is voltage selector plug. Somebody decided they should be removed from the electrical code. Your left with the voltage selecting fuseholders. try schurter. Steve

Ouch, ouch, ouch ... really? So they are gone for good? > ...

The fuse holders are large panel mount devices but we'll have no panel. I could cook up an electronic auto-selector but that would probably blow the cost target as well. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.

Why a slide switch will not do? You can find voltage selector slide switches in which the slider is burried so deeply it can only be operated by a small screwdriver or something like that. Sliding it accidentaly seems next to impossible. petrus bitbyter
