Abstract:

An effective seal against the infiltration of foreign matter into a push-pull remote control is provided by a spring-loaded ring seal disposed in contact with a slidable end rod of the control. The ring seal is formed by a plastic C-shaped channel which holds a metal helical spring. One of the two spring-loaded side walls of the C-shaped channel presses against the cylindrical surface of the end rod and thus impedes the penetration of dust and vapors into the remote control.
