A switch structure comprises a gripper, a splinted trough and a cutoff circuit. In another aspect, the present application discloses a light source comprising an LED die having an emitting surface and a high index optical element optically coupled to the LED die and shaped to direct light emitted by the LED die to produce a side emitting pattern having two lobes. The critical path of a conventional RSSE implementation is broken up into at least two smaller critical paths using pipeline registers.
