Abstract
A water resistant actuating mechanism for a plunger type limit switch using a bowed spring to activate the plunger of a plunger type switch mounted within an actuating mechanism housing includes a flexible seal for covering the hole or opening in through which the bowed spring extends. The seal may be dome shaped and cover a circular opening. A glide or shoe is positioned on or connected to each end of the spring and are held in place between an upper wall of the housing and a backing sheet connected to the housing. The glide reduces the amount of deflection of the bowed spring required to activate the plunger type switch such that the additional thickness added by the flexible seal does not increase the overall required thickness of the actuating mechanism.
