Abstract: Drug delivery devices are described that include an escapement activation assembly. The escapement activation assembly includes a slide having a plurality of pallet engagement portions and a switch engagement portion and a pallet having a plurality of slide engagement portions. A drive is coupled to the pallet to cause the pallet to move relative to the slide to move the plurality of slide engagement portions into and out of engagement with the plurality of pallet engagement portions to allow the slide to move along a path within the drug delivery device. Movement of the slide can cause the switch engagement portion to move out of engagement with an activation trigger of a mechanism of the drug delivery device.
