  • the electrical switches 120 , 122 when actuated, may cause operations to be carried out by the controller 116 .
  • the operations carried out by the controller 116 may be related to communication, derailleur pairing, trim and/or shift operations, for example, and may generate signals to initiate or elicit an action and/or response from various mechanisms of a bicycle such as electromechanical derailleurs (see FIG. 23 ).
  • a first electrical switch 120 includes a contact 126 , which may be disposed on the PC board 113 , an electrical dome switch element 128 , or the like, positioned to contact the contact when depressed and a retainer 130 connected to the PC board to maintain alignment of the electrical dome switch element with the contact. While other types of electrical switches may be used, dome switches like the one illustrated are robust, reliable and provides a desired amount of feedback to the user.
  • the first electrical switch 120 may be used for an operation of the control assembly 30 that will be performed more frequently and potentially forcefully, such as the initiation of a shift operation.
  • a second, optional, electrical switch 122 may also be a dome switch.
  • the second electrical switch may be a smaller and more self-contained switch that is intended to be used less frequently than the first switch 120 .

  • the cover 108 includes one or more opening 132 A, B, each of which includes a respective button actuator 134 A, B disposed therein.
  • the button actuators 134 A, B operate through the material of the seal 110 . In this manner, the integrity of the seal 110 is not compromised.
  • an actuator spring 136 may be provided on actuator 134 A.
  • the actuator spring 136 may be held on the actuator 134 A by a projection 138 that may be sized and shaped to retain the spring in alignment and/or engagement with the actuator. When the actuator spring 136 is sufficiently compressed, it urges the actuator 134 A toward the seal 110 and electrical dome switch element 128 , causing the dome switch element to close with the shift switch 126 and actuate the electrical switch 120 .
  • FIGS. 14 and 15 show that the seal 110 may include raised or thickened sections 138 A, B, which are positioned between respective actuators 134 A, B and electrical switches 120 , 122 to encourage effective transfer of force from the actuators to the switches. Also, the means of actuating the electrical switches 120 , 122 is shown.
  • the shift lever 37 and in particular the distal end 37 B thereof, may be positioned closer to the outboard side 48 of the brake lever 36 .
  • the inboard side 53 of the brake lever 36 may include a spring holder 140 for the end of the actuator spring 136 opposite the button actuator 134 A. When the shift lever 37 is urged toward the inboard side 53 the spring 136 is compressed between the holder 140 and the actuator 134 A.
  • the compression of the spring 136 causes the actuator 134 A to press against the seal 110 and the thickened section 138 A thereof depresses the dome switch element 128 of electrical switch 120 .
  • the actuation of electrical switch 120 sends a signal through associated circuitry as is well known to be acted upon by the controller 116 according to instructions provided thereto. It is believed that the presence of separate levers for brake and shift operations may be comfortable to bicycle operators who are used to mechanical shifting systems having separate levers for the brake and shift functions.
