Are these wall switches still legal to use?
They were real popular when I was a kid, and would like to put them in
my house. They are the old style push buttons.
See photo here.
This is a small point but in some cases it becomes important. No AHJ
can require you to use only UL listed equipment. They have to accept
the listing marks of other recognized electrical testing laboratories.
Some specialized and historic parts manufacturers turn to ETL and other
smaller labs to keep cost down on small production runs of unique items
but that does not make them unlawful to use. The applicable language
from the US NEC is
110.3 Examination, Identification, Installation, and Use of Equipment.
(A) Examination. In judging equipment, considerations such as the
following shall be evaluated:
(1) Suitability for installation and use in conformity with the
provisions of this Code
FPN:Suitability of equipment use may be identified by a description
marked on or provided with a product to identify the suitability of the
product for a specific purpose, environment, or application. Suitability
of equipment may be evidenced by listing or labeling.
(2) Mechanical strength and durability, including, for parts designed to
enclose and protect other equipment, the adequacy of the protection thus
(3) Wire-bending and connection space
(4) Electrical insulation
(5) Heating effects under normal conditions of use and also under
abnormal conditions likely to arise in service
(6) Arcing effects
(7) Classification by type, size, voltage, current capacity, and
(8) Other factors that contribute to the practical safeguarding of
persons using or likely to come in contact with the equipment"
Notice that Underwriters laboratories is not mentioned by name The
reference to listing or labeling in the fine print note are not part of
the code itself and are therefore not enforceable as such and the
listing and labeling of one lab is a valid as any other for code
> But neglecting what local code enforcement say require:
Local enforcement can only require what the law requires. The maxim of
the law is that whatever is not forbidden is allowed. Unless the local
inspector can quote you chapter and verse then screw your courage to the
sticking point and demand a written corrective order. After there
office knows you will appeal arbitrary and capricious rulings they will
be far more careful about what they try to make you do. Some may be
vindictive and never cut you any slack but if you are a qualified
electrician that does not do shoddy work you shouldn't need any slack.
Your work either complies with the code as adopted or it does not.
Well we aren't no thin blue heroes and yet we aren't no blackguards to.
We're just working men and woman most remarkable like you.
The ones you remember as a kid were not sealed, and would not be legal
to install today. However, the new switches you cited are essentially
replicas, built to today's standards, and UL listed.
If you're willing to spend $20 for a light switch, knock yourself out!

They advertised them as UL listed, and I'm guessing that if you follow
the manufacture's instructions and the switches limitations (120v15a
as listed) it should be ok.
btw, they look interesting, very unique.
