Rocker arm assembly, compliance capsules, actuators, and support structures

A compliance capsule for actuating a switchable capsule in a valvetrain system, comprising:

• an outer tubular member defining a cavity and comprising a first end and a second end opposite to the first end;
• a first body slidably disposed in the cavity adjacent the first end and connected to the switchable capsule to selectively transfer a motion to turn the switchable capsule on or off, wherein the first body comprises an internal cavity;
• a second body at least partially and slidably disposed in the cavity adjacent the second end and configured to receive a force from an external source;
• a compliance spring disposed between the first body and the second body;
• and
• an inner capsule formed as an inner tubular member, the inner capsule comprising:
• a first capsule end at least partially disposed inside the internal cavity of the first body;
• and
• a second capsule end provided opposite the first capsule end and configured to receive the second body.
