Dielectric Strength
H/I-Series Toggle Switches
UL/CSA: 1000V-live to dead metal
General purpose workhorses with options tailored to meet
parts
most any need. Ratings to 17A 125VAC, various actua-
tor, bushing, termination, and circuit choices allow this
toggle to easily integrate into a variety of different applica-
tions. The H/I-Series has a storied history in the Food
service, Generator, Industrial Control, and Office
Automation markets and are appropriate for usage in low
voltage DC applications as well.
