Circuit board latch system
A method according to one embodiment may include providing a circuit board assembly comprising a circuit board and a rotatable knob and at least one latch coupled to the knob via a linkage. The method of this embodiment may also include moving the at least one latch to a retracted position by rotating the knob, and inserting the circuit board assembly into a chassis. The method may then include moving the latch to an extended position. Of course, many alternatives, variations, and modification are possible without departing from this embodiment.
