       11 . A wearable infusion device comprising:
 a reservoir that holds a liquid medicament;   an outlet port that delivers the liquid medicament to a patient;   a pump that displaces a volume of the liquid medicament to the outlet port when actuated; and   a control that actuates the pump, the control comprising an actuator arranged to provide a perceptible indication that the pump has been actuated.   
   
   
       12 . The device of  claim 11 , wherein the perceptible indication is a tactile indication. 
   
   
       13 . The device of  claim 12 , wherein the control comprises a snap action actuator and the tactile indication is that of snap action. 
   
   
       14 . The device of  claim 11 , wherein the perceptible indication is an audible indication. 
   
   
       15 . The device of  claim 14 , wherein the audible indication is a sharp sound. 
   
   
       16 . The device of  claim 14 , wherein the control comprises a snap action actuator and wherein the audible indication is a snap sound. 
   
   
       17 . The device of  claim 11 , wherein the control includes a pair of actuator buttons arranged to require concurrent operation for pump actuation. 
   
   
       18 . The device of  claim 17 , wherein only one of the actuator buttons causes the actuator to provide a perceptible indication that the pump has been actuated. 
   
   
       19 . The device of  claim 18 , wherein operation of the other one of the actuator buttons enables actuation of the pump. 
   
   
       20 . The device of  claim 17 , wherein the perceptible indication is a tactile indication. 
   
   
       21 . The device of  claim 17 , wherein the perceptible indication is an audible indication. 
   
   
       22 . A wearable infusion device comprising:
 a reservoir that holds a liquid medicament;   an outlet port that delivers the liquid medicament to a patient;   a pump that displaces a volume of the liquid medicament to the outlet port when actuated; and   a control that actuates the pump, the control comprising a pair of actuator buttons arranged to require concurrent operation for pump actuation and providing a combined perceptible tactile and audible indication that the pump has been actuated.
