Abstract: A safety lock for a centrifuge prevents the opening of the rotor housing if the rotor is in operation and conversely prevents the rotor from being operated if the rotor housing is not latched and locked. A plunger linked to a cam follower is used to lock a door latch and to sense its latched or unlatched condition. The position of the cam follower and hence of the plunger is sensed by plural switches. The cam follower is biased by a spring to normally urge the plunger into a locking position with the latch. A drive cam, actuated under the control of the plural switches, withdraws the plunger to unlock the latch and releases the cam follower to permit the plunger to snap into a locking position.
