Control device having locking selector means

摘要

A control device having a support and a first selector member rotatably carried by the support. A second selector member is rotatably carried by the support and is axially movable relative to the support and the first selector member. The selector members are coupled together in a manner to cause the first selector member to rotate in unison with the second selector member when the second selector member is rotated. A pair of spaced spring members are disposed between and respectively engage the selector members to tend to maintain the second selector member axially away from the first selector member. The first selector member has a cylindrical part extending therefrom and the second selector member has a C-shaped shaft rotatably disposed against the cylindrical part of the first selector member. A tang extends radially outwardly from the second selector member and is received between two spaced apart abutments on a surface of the support when the second selector member is in one rotational position thereof so that the second selector member is locked in that one rotational position until the second selector member is axially moved toward the first selector member a certain amount.
