An arrangement is provided to protect an electrical switch from the deleterious effects of ice formation that inhibits switch operation. In a preferred arrangement, an ice shield is provided that protects the current-carrying contact structures and other operative elements of the switch from ice buildups. In one specific arrangement, as the switch is moved from the open position to the closed position, the ice shield moves away from the contact structure of a moving contact of the switch to permit unfettered engagement with a stationary contact structure of the switch. |
