Ice shielding means for an outdoor, high voltage disconnect switch assembly having interengaging moveable and stationary members, comprising:
- rigid support means coupled to the stationary portion of the switch and extending generally vertically therefrom;
- flexible shielding means having one side thereof fixedly coupled to said support means and aside opposite said one side free and unsupported so as to extend above the stationary portion of the switch and in the path of the moveable portion thereof;
- whereby movement of the moveable portion of the switch pursuant to disengagement of the switch members temporary elastically deforms the shielding means.
In a high voltage disconnect switch of the outdoor type and including a stationary and a moveable interengaging switch portion, an ice shielding means comprising;
- a rigid support member coupled to said stationary portion of said switch and extending generally vertically therefrom;
- a flexible shield means coupled to and supported by said rigid support member and extending generally horizontally therefrom above the point of engagement of said moveable and stationary members of said switch;
- said flexible shield means extending in the path of said moveable member of the switch.
