Patent ID: 7140515

Claim:
A manually manipulable actuator apparatus, comprising: a body having at least one wall element having a length generally extending along a first axis and a height extending along a second axis orthogonal to said first axis, wherein said height varies along said first axis; and a manually manipulable element having a button portion for human digital manipulation and at least one wing portion extending outwardly from said button portion, said at least one wing portion including a leg that overlaps said height of said wall along said second axis, wherein said manually manipulable element is movable along said first axis between a first position in which an operative element is in a non-actuated condition and a second position in which the operative element is in an actuated condition, wherein said at least one wall element has a first height at said first position and a different second height at said second position, and wherein said at least one wall element cooperates with said leg of said at least one wing portion to constrain movement of said manually manipulable element along a third axis orthogonal to said first and second axes while said manually manipulable element is moved between said first and second positions.
