Abstract
An electrical switch includes an operating member carrying moving contacts which face, in opposite directions, two rows of fixed contacts. The operating member moves the moving contacts into and out of contact with the fixed contacts. Each moving contact may have opposite ends for contacting two adjacent fixed contacts on a corresponding side of the operating member. Springs provided between the moving contacts and corresponding side of the operating member bias the contact ends into contact with the corresponding rows of fixed contacts.
