  • the contact members for the main switch are enclosed at all times in housings which protect them on all sides, except the confronting vertical faces so that the contacts are reasonably well protected from all weather conditions. Should ice or sleet form upon the exposed portion of the blade 19, this will be easily broken when theblade is operated, since the leverage at the joints is the same at the extremity of the switch as it is at the joints closest to the operating mechanism. The switch never moves out of a direct line between the two contacts so that it does not swing toward adjacent objects as is the case with an ordinary pivoted switch.
