SUBMERSIBLE SWITCH POINT MACHINE

      
Application Number US2019019986
Publication Number 2019/177778
Status In Force

Abstract

An improved switch point machine is provided which can seal out water, even if the machine itself becomes submerged. The operating rod and the point indicating rod that extend out of the switch box housing should be ground round and have a smooth surface for an improved seal. Those rods are preferably chrome plated. Dynamic hydraulic seals can be used to seal out moisture. Internal components, within the switch box housing, should also be sealed to be water resistant in the event water does enter the housing.
