Modular elements employing latches secured by linkages are disclosed. A modular element may include a chassis body in communication with a latch, control body, and control arm of the modular element. The modular element is removable from or secured to an enclosure using the latch. The latch may remain secured to the enclosure in a locked mode by being rotated to engage a control catch of a control arm of a linkage. By connecting the control arm to the control body with a rigid member connected to the control body with first and second rotary joints, the rigid member transforms a control body movement into a rotary motion of the control arm to disengage the control arm from the latch. In this manner, the modular element may be disengaged from the enclosure to facilitate upgrades or maintenance of electronic components supported by the chassis body.
