Abstract
A transfer switch that absorbs the kinetic energy of a toggle mechanism within the transfer switch just before moving contacts on the toggle mechanism engage a set of stationary contacts. The transfer switch includes output contacts, primary input contacts, secondary input contacts and a toggle mechanism. The toggle mechanism includes moving contacts that alternately connect the output contacts with the primary and secondary input contacts. The transfer switch further includes a dampener that reduces the kinetic energy of the moving contacts before the moving contacts engage the input contacts.
