OG exemplary drawing
 
1. A prism actuator, comprising:
a prism operational to fold an optical path from a first direction to a second direction;
a top sub-assembly including the prism, a first pin, a second pin, a first yoke and a second yoke; and
a bottom sub-assembly including a first magnet and a second magnet,
wherein the top sub-assembly is configured to rotate relative to the bottom sub-assembly around a first rotation axis perpendicular to both the first and the second direction,
wherein the first yoke is fixedly attached to the first pin and the second yoke is fixedly attached to the second pin, and
wherein the first yoke is pulled to the first magnet and the second yoke is pulled to the second magnet such that the top sub-assembly is prevented from detaching from the bottom sub-assembly.
