H/I-Series Toggle Switches
Dielectric Strength
General purpose workhorses with options tailored to meet ^{UL/CSA: 1000V-live to dead metal}
most any need. Ratings to 17A 125VAC, various actua- ^parts
tor, bushing, termination, and circuit choices allow this ^{Electrical Life}
toggle to easily integrate into a variety of different applica- ^{50,000 cycles- maintained}
tions. The H/I-Series has a storied history in the Food ^{25,000 cycles- momentary}
service, Generator, Industrial Control, and Office
Mechanical Life
Automation markets and are appropriate for usage in low ^{100,000 cycles}
voltage DC applications as well.
