Patent ID: 6941641

Claim:
A method for mounting an arm to an actuator, comprising the steps of: providing an actuator assembly having at least one spacer and at least one arm, the spacer having an annularly shaped lip with first radius extending from a planar surface of the spacer, the lip having a different cross-sectional area than the planar surface of the spacer from which the lip extends, and at least a first detent formed in a perimeter edge of the lip and a reference location diametrically opposed from the center of the detent, and the arm having first and second resilient fingers at a proximal end of the arm, the fingers having inner surfaces that define a substantially annularly shaped opening between the first and second fingers, the annularly shaped opening having a second radius that is less than the first radius and at least the first finger having an engagement member extending from the inner surface into the annularly shaped opening; positioning the arm to locate the engagement member of the first finger within the first detent; and rotating the arm about the engagement member and toward the lip while the engagement member is within the first detent to expand the first and second resilient fingers from a neutral state and to engage the first and second fingers in a stressed state with the lip and with the second finger extending beyond the reference location to mount the arm to the lip.
