Definitions

  • the invention provides a modular designed push button switch, comprising an electrical contact module, an enlarged halo to accommodate a switch actuator and a legend plate, and a halo adapter interfacing the halo with the electrical contact module, whereby halo and halo adapter define a housing for the switch actuator which actuates via an axial movement the contact carrier of the electrical contact module.
  • the push button assembly defined above provides easy assembling as well as disassembling from the back of a push button face plate, in order to replace damaged components and/or to change component colours, identifying legend plates and the like.
  • a push button assembly of this kind is known from the US-A-4 742 198.
  • a face plate includes a single opening for each push button assembly, with the push button assembly including a halo which interfaces the assembly with the face plate, snugly extending into the face plate opening.
  • a halo adapter interfaces the halo with an electrical switch which is actuatable via axial movement of a contact carrier.
  • the halo and halo adapter nest to cooperatively define a housing for a switch actuator, eliminating the need for special tooling.
  • the halo and halo adapter define first and second axial travel limits for the switch actuator, respectively, with the electrical switch biasing the switch actuator to the first travel limit.
  • the switch actuator includes an actuating portion, which is completed by a lens.
  • actuating portion is suitably fixed to the actuating portion, such as by ultrasonic welding.
  • actuating portion and lens are translucent to transmit light to indicate to the user that the button has been actuated, e.g., that an elevator call has been registered, when the push button assembly is used in an elevator application.
  • the invention has the purpose of the creation of a push button switch expanding the field of application of the modular concept and enabling an economical and simple production of the push button components.
  • the advantage attained by the invention is to be seen substantially in that there is only one type of button and lens necessary to quickly and easily assemble push buttons with different legends and colours without the use of special tools.
  • the push button switch comprises an electrical contact module 1, a halo adapter 2, a switch actuator 3 and an enlarged halo 4.
  • Electrical contact module 1, halo adapter 2 and the enlarged halo 4 are described in detail in the document US-A-4 504 713 and in the document US-A-4 742 198.
  • a face plate 5 includes an opening 5.1 and fastener means 5.2 fixed to the inner surface for securing the push button switch. As illustrated, opening 5.1 has a substantially rectangular configuration with half circle endings.
  • Halo 4 and halo adapter 2 are constructed to nest snugly together to form a switch actuator housing within which the switch actuator 3 is disposed in a snug but axially slidable guided relationship relative to the halo elements.
  • the halo 4 includes a flange 4.1 carrying a first projection 4.2 and a second projection 4.3 surrounding a push button opening 4.5.
  • the first projection 4.2 has a substantially square configuration and is configured to snugly enter halo adapter 2 to form the switch actuator housing.
  • the second projection 4.3 is configured to snugly enter opening 5.1 in the face plate.
  • the depth of the second projection 4.3 is at least equal to the thickness of the face plate 5.
  • Electrical contact module 1, halo adapter 2 and enlarged halo 4 show mounting ears 1.1; 2.1; 4.4 with fastener means receiving openings which are aligned with the fastener means 5.2.
  • the switch actuator housing part of the halo adapter 2 is formed by a recess 2.2 having a square configuration and by a wall 2.3.
  • the wall 2.3 shows on each side a rectangular opening 2.4 enabling the actuating function of the push button.
  • a lamp 1.2 illuminates the switch actuator 3 through a central opening 2.5 in the wall 2.3.
  • the switch actuator 3 or push button includes a base portion 3.1 having on the halo adapter end actuating legs 3.2 and on the halo end an actuating portion 3.3.
  • the actuating legs 3.2 extend outwardly from the halo adapter end and engage via the rectangular openings 2.4 a spring biased contact carrier 1.3.
  • a cylindrical lens cap 3.4 is snugly but slidable placed over the round actuating portion 3.3.
  • On the halo end a lens 3.5 configured by a radius on the top surface of the lens cap 3.4 completes the lens cap 3.4 which is dimensioned to slidably enter the push button opening 4.5 in halo 4.
  • the lens 3.5 transmits the indicating light of the lamp 1.2 to the user.
  • a collar 3.6 surrounds the opening of the lens cap 3.4 and transmits an actuating force applied to the lens 3.5 to the base portion 3.1.
  • actuating portion 3.3, lens cap 3.4 and push button opening 4.5 have a round configuration.
  • teachings of the invention apply equally to alternative configurations, such as square.
  • Fig. 3 depicts the assembled push button switch as hereinbefore explained.
  • the cross sectional view shows the switch actuator 3 disposed in the switch actuator housing.
  • actuating legs 3.2 engage the spring biased contact carrier 1.3 and the contact carrier 1.3 thus pushes the switch actuator 3 against the first projection 4.2 of the halo 4, whereby the collar 3.6 of the lens cap 3.4 is pressed against the first projection 4.2 by the base portion 3.1.
  • An actuating force applied to the lens 3.5 overcomes the bias of the contact carrier 1.3 causing the switch actuator 3 to travel a predetermined distance inside the switch actuator housing.
  • the switch actuator 3 comes to rest as soon as the base portion 3.1 reaches the wall 2.3 of the halo adapter 2, preventing an excess pressure on the contact carrier 1.3.
  • the surface of the top of the actuating portion 3.3 is flat so that legends can be printed, hot stamped or engraved on it.
  • the transparent lens cap 3.4 is placed over the actuating portion 3.3 to protect the legends. All the plastic components of this push button switch are moulded using polycarbonate in different colors.
