ABSTRACT:
First and second counterbalanced contact elements rotate about a common axis so that shock and vibration induced loads produce negligible moments on the contact elements with respect to their axis of rotation. Springs are included and arranged for snap opening and closing of the contact elements to minimize electrical arcing during opening and closing of the contacts.
