An ambidextrous actuating mechanism configured as a mechanical interlock may be adapted to a battery operated light emitting device for mounting forward of the trigger guard of a firearm. The mechanism includes first and second mechanically coupled pivotable switch actuators disposed under and on either side of the barrel of the firearm. Operation of either one of the first and second actuator levers locks the other actuator from pivoting, thereby eliminating ambiguity and overridden operations in the control of the light emitting device. The operating motion of both actuators, either up for ON or down for MOMENTARY, is the same for both actuators. An alternate embodiment provides functionally equivalent electronically interlocked actuators.

A multi-way input device includes a first interlocking member, a second interlocking member, a hollow frame within which the interlocking members are mounted, and an operating shaft inserted through both a slit of the first interlocking member and a slot of the second interlocking member. The device also includes first and second sensing components capable of being operated respectively through the first and second interlocking members when rotating by operation of the operating shaft, along with third sensing component capable of being operated through the second interlocking member when pivoting by operation of the operating shaft. The device also includes an articulation member that is rotatably supported by the hollow frame around an axis. The second interlocking member is supported by the articulation member to form a mobile unit that is rotatable. The second interlocking member is also pivotally mounted on the articulation member.

Various embodiments include a transmission element for a spring return of an actuating drive comprising: a toothed wheel element with teeth at least in sections; and a locking element including a locking section for locking engagement in the teeth of the toothed wheel element to prevent a rotation of the toothed wheel element in a return direction. The locking element includes a safety element mechanically operatively connected to the locking section and elastically deformable in order to release the locking of the toothed wheel element by elastic deformation of the safety element at a torque of the toothed wheel element in the return direction greater than a safety torque limit.
