Question

What is snap-action?

Answer

Snap action is a mechanism that enables a movable contact to quickly travel from one fixed contact to another fixed contact regardless of the speed at which the Switch is operated.

The high switching speed shortens the time arcing is maintained.

Contact wear and damage are reduced, so stable characteristics can be obtained.

Large-capacity switching can be performed with compact models.
