Definitions

  • the present invention relates to a push button switch with a watertight housing and interior lighting for mounting on a printed circuit, which is provided with at least one fixed contact of the switch and a light source, and wherein at least the carrier of the movable contact is tappet-shaped and centrally located on the inside on one side closed translucent socket with an outer guide flange is guided lengthwise.
  • Such pushbutton switches are used in machine controls, switch panels, measuring stations etc.
  • the lifespan of the switches includes limited due to the materials used. In particular, after a long period of operation, they only insufficiently meet the high requirements for tightness.
  • the housing is formed by a flexible spherical cap open at both ends with a central guide collar which radially surrounds the bushing.
  • the design according to the invention allows the space to be sealed in the housing of the switch to be reduced and thus reliable sealing elements to be provided.
  • the attachment of the calotte according to claim 4 increases the stability of the system.
  • Sockets made of a light-conducting material result in improved light emission and thus an improved display compared to simple, transparent sockets.
  • the light-conducting material according to claim 8 results in a particularly high luminous efficiency.
  • Keycaps according to claim 9 can be easily labeled and / or embossed.
  • the guidance according to claim 11 allows the bush to be guided in a particularly smooth manner and defined on the stop.
  • a transparent key cap is designated by 1. This has a trough 1 'to center the finger pressing the button.
  • a central clamping sleeve 1a is used to center and fix the key cap 1 on a guide bushing 4. Furthermore, the key cap 1 has annular recesses 1b and 1c and a shoulder 1d serving for power transmission, cf. Fig. 3.
  • the guide bush 4 has on its upper side a closed part 4 'and is guided on one side in a conical sliding bore 5a of a guide flange 5.
  • the guide flange 5 has a concentric recess 5b which is delimited by a stop 5c.
  • the guide flange 5 is centered and fixed by a clamping ring 6 with clamping elements 6a.
  • a flexible dome 2 sits with its clamping and fastening groove 2b in a bore 3a of a mounting plate 3, which is usually part of an apparatus housing.
  • the calotte 2 has on its upper sides a guide collar 2a which surrounds the guide bush 4 peripherally and on whose outside shoulder 1d the key cap 1 rests.
  • the clamping ring 6 fixed, held between the inside of the calotte 2 and the guide flange 5, the whole.
  • a circuit board 8 with a light source 9, an LED, and with a split contact ring 10 arranged around it, which is aligned with the opposite contact ring 7a.
  • the light source 9 is connected to the printed circuit of the printed circuit board by feed lines 11, via solder joints 12.
  • the design of the guide bushing 4 can be discussed in detail with reference to FIG. 2: Here it can be seen that it has a centering flange 4a and a stop flange 4b at the bottom and a screw 4c at the top.
  • the key cap 1 shown again in FIG. 3 clearly shows the annular recesses 1b, 1c, they serve to improve their transparency.
  • the clamping sleeve 1a is provided, which is dimensioned so that it can be placed non-positively and positively on the closed part 4 'of the guide bush 4 and the upper part of the turn 4c.
  • a central recess 1 ⁇ has a shoulder 1d which, according to FIG. 1, rests on the guide collar 2a of the calotte 2.
  • the top view Fig. 4 shows the key cap with an exemplary lettering ABC.D.
  • the clamping ring 6 is shown in section in FIG. 5. In connection with FIG. 6 it can be seen that here three lobed clamping elements 6a are arranged in a circle at an angle of 120 °.
  • the mode of operation of the switch is very simple: the elasticity of the cap 2 causes the key cap 1 to be moved into its upper end position via its guide collar 2a.
  • the guide bush 4 held in it is also in the end position, i.e. with its stop flange 4b up to the stop 5c of the guide flange 5.
  • the spring action of the calotte is overcome; the contact ring 7a bridges the fixed contact 10 and opens or closes, among other things. the feed connection to the light source 9 and thus causes the illumination of the key cap 1 and the printed name ABC.D.
  • the key caps 1 are particularly easy to replace by simply pulling them off.
  • silicone elastomers of the types silicone rubber Q and polybutadiene rubber BR (Maagtechnik AG, D Wegner), which undergo their shaping by compression or transfer compression processes known per se, have proven successful for the production of the domes.
  • the light-guiding guide bush 4 consists of a polycarbonate (acrylic glass) and is produced by injection molding.
  • ABS Acrylonitrile-butadiene-styrene copolymers
  • the contact rings 7a and 10 are made of conductive silicone rubber (type KE3801, Maagtechnik AG) and with their carriers made of non-conductive silicone rubber (KE 9514) and glued by vulcanization.
  • the fixed contact ring 10 can of course also consist of the metal-clad printed circuit board.
