- Since our
first switch pole was filed out by hand back
in 1953, BOLTSWITCH has continually
contributed to the science of switch building.
originally set out to build a better 400 amp
switch, realizing that knife switches were
being outmoded and breakers have limited
- The original
400 amp switch performed well in tests and led
us right into 600, 800 and 1200 amp and the 30
through 200 amp sizes.
- Our small
switches our performed any switch on the
market. We provided the industry's first
UL listed switch marked as to its suitability
for use on circuits having high available
- Our proven
principals were then applied to larger
ampacity switches. We were the first
with Quick-Make, Quick-Break operators on all
sizes of switches through 4000 amperes.
- Our large
switches were the first to pass the UL tests
at 600 volts.
- We were the
first with a Shunt-Trip operator.
- We have
invested an extraordinary amount of time,
money and thought into our design and test
programs, and the switches we produce are
unique, in the true sense of the word.
- Though our
interest in safety may at times exceed our
interest in sales, we have been able to grow
with a feeling of satisfaction.
