Switching your project to go

The ITW Butterfly Double Break Switching provides the highest standard of reliability for all industrial and military products. Butterfly double break switching provides extra long life, two circuit control and higher current capacity.

In operation, the ITW Butterfly Switch’s contact blades flex like a butterfly’s wings to actuate the spring held blades that operate with a positive “snap” and a corresponding linear wiping action at each contact point.  The result is simultaneous opening and closing without contact welding.

Butterfly Double-Break switching can break high inductive loads on DC current applications.  Two contact breaks in series rapidly increase current resistance and current interrupting capacity.  By using a coiled extension spring, Butterfly Double-Break Switches increase both electrical capacity and mechanical life.
