1. An information handling system comprising:
a base of a monitor stand, the base including a first plate and a swivel plate that is rotatable with respect to the first plate;
a swivel lock mechanism to lock the swivel plate at a predetermined location with respect to the first plate;
a circular guided cam profile on the swivel plate;
a lock plunger of the swivel lock mechanism, the lock plunger being in a forward position when the swivel lock mechanism is engaged;
a recessed portion in the circular guided cam profile to receive the lock plunger of the swivel lock mechanism when the lock plunger is aligned with the recessed portion and the swivel lock mechanism is engaged, the lock plunger entering the recessed portion to thereby lock the swivel plate at the predetermined location; and
wherein the lock plunger stays in contact with the circular guided cam profile as the swivel plate is rotated while the swivel lock mechanism is engaged;
wherein the swivel lock mechanism further comprises,
a first spring that exerts a force on the lock plunger to force the lock plunger into the forward position when the swivel lock mechanism is engaged;
an engagement button to engage and disengage the swivel lock mechanism, the lock plunger of the swivel lock mechanism being in a rearward position and thereby spaced apart from the circular guided cam profile when the swivel lock mechanism is disengaged;
a second spring and a third spring, the second and third springs configured to exert a force on a body of the swivel lock mechanism to cause the swivel lock mechanism to move backward when the engagement button is pushed while the swivel lock mechanism is engaged, the engagement button being pushed thereby resulting in the swivel lock mechanism becoming disengaged.
