The poor bypass is also a common problem according to someone known to

issues.

If there is non-conductive grease in other , otherwise 240V rated

switches,
then that could be a generic problem with all switch makes, used for
low

V,
low A purposes.



If the switch is rated for 240 VAC, then it wasn't made to switch
audio. You need self wiping contacts, not ones that burn away oxide when
switched.

I thought standard mains electric wiring pattressed switches were wiping
contacts.

Had to clean out the graphite grease - not high enough ohmage between the
static contacts. Stuffed more plain silicone grease in the ratchet section
and left the contacts area dry well low V, low A switches are usually dry.

OK. I spoke to the guy who owns the shop today, and asked him how much
trouble he gets with pedal bypass switches. He expressed considerable
surprise at the question, and said "none, really". He reckons that he sells
hundreds of pedals, and very rarely has any comeback as a result of bad
bypass switches. He has been in the business a long time, and his shop is
very busy. He is a musician himself.

In fact, he said that what he described as "the clunk-clunk hit it with your
foot type switch" was "remarkably reliable considering the amount of use and
abuse it gets with a working band", which was pretty much what I said. He
reckons that the only real problem that he's had, was a couple of years ago
when he had a bunch of 'bad batch' pedals that bounced back and forth
between him and Marshall, who are just up the road from us. So I reckon that
the guy that wrote the article that you cited, is either over-emphasising
the true size of the 'problem' with the switches, or has just been plain
unlucky.
