Based on CU20/CP model, it is a bistable locking bolt where the movement from initial (unlocked) to final position (locked) is made by electromagnetic forces. The return to initial position takes place by an inverse polarizing pulse combined with external forces or by an incorporated spring.

The bistable solenoid has two working and mantained positions without voltage. One will be held by a permanent magnet system and the other one by a return spring or external forces. 

The bolt has a slip with anti-rotation system and frontal, rear and lateral fixations, and the guide has been reinforces for a correct performance in case of radial stress.
