ABSTRACT:
There is provided structure for use in adjusting certain design parameters of a relay during initial assembly of the relay. The structure includes an adjustment member insertable between a bobbin and a core. The adjustment member is preferably U-shaped having arms straddling the core and a backspan which acts as a stop to define the travel of an armature. The adjustment member is driven between the bobbin and core and permanently fixed in place when the desired parameters have been attained. The armature is forced against the motor assembly until the desired design parameters are obtained and the motor assembly is then permanently fixed in place within the relay. An armature is forced against the core moving it within the bore of the bobbin until the desired parameters have been obtained. Thereafter, the core is permanently fixed in position within the bore of the bobbin.
