AI Technical Summary

Problems solved by technology

In many cases, achieving these relationships will be complicated by the fact that normal manufacturing tolerances alone may be greater than the total travel of the switch (return plunger travel plus travel difference plus maximum allowable overtravel) requiring the use of expensive and complex mounting bracket system

Abstract

A sealed dual plunger switch assembly includes two switch sub-assemblies comprising plunger actuating mechanisms and basic switches. The sub-assemblies can be inserted into an overall enclosure using shims in order to position their operate points in the desired range relative to the enclosure's mounting surface. The enclosure is then sealed using a combination of covers, gaskets, O-rings, connectors and potting. The sub-assemblies individually and / or simultaneously receive actuation inputs within a fixed distance from the assembly's mounting surface.

Description

technical field [0001] Embodiments generally relate to electrical switches. Embodiments also relate to plunger actuation mechanisms for use in switchgear. Embodiments also relate to sealed switch subassemblies within a common housing for maintaining actuation inputs at different plunger positions, operating simultaneously within a fixed distance from a mounting surface of the assembly. Background technique [0002] Many types of switching mechanisms are used in residential, commercial, industrial and military applications. A particular application of this type of switch mechanism involves a push button switch comprising a plunger movable along an axis relative to a base and which actuates a switch member when the plunger is depressed. Typically, the plunger is connected to a button depressible by a human finger. Some switch mechanisms actuate the switch each time the button and plunger are depressed, while others, known as alternating-action devices, actuate on one press ...
