Definitions

the invention relates to a switching mechanism for a rotary coding switch, with a symbol or number wheel arranged within a housing, a switching element and a latching device, which essentially comprises a ratchet wheel and at least one ratchet lever, which is movably mounted at one end in a bearing element of the housing and is pulled with the other end by the restoring force of a spring into the locking recess of the locking wheel.
each detent lever has a semicircular recess into which a bearing part, which is mounted in the housing and is designed as a swivel element, engages.
the detent levers are pressed into the detent recess by a compression spring, which is supported essentially on the switch housing, with the molded-on extension.
this latching device in the present embodiment is not suitable for a multi-position selector switch (rotary coding switch).
the invention has for its object to provide a switching mechanism for a rotary coding switch mentioned in the introduction, in which the switching and latching elements ensure a switching process that can be transferred exactly to the symbol or number wheel. This requirement should also be guaranteed in difficult environmental conditions (operability with gloves).
the coding rotary switch 1 shown in Figures 1 to 4 consists essentially of a housing 10, a symbol or number carrier 35, a circuit board 65 and a switch 70 arranged in the housing 10, which a ratchet wheel 25, a gear 30 and two mirror images , includes detent levers 40 and 50 arranged symmetrically to one another and can be actuated by a switching element 20 which is rotatably mounted laterally on the one housing wall.
FIG. 1 shows a sectional view of the rotary coding switch 1 and one can see the housing 10 formed from an end wall 11, a rear wall 12, an upper and lower wall 13 and 14 and a side wall 15 and preferably made of plastic.
the housing On the side opposite the side wall 15 the housing has an opening, which is not described in any more detail and which is closed by means of the circuit board 65 after the switching mechanism has been installed.
the two walls 13 and 14 and the end face 11 of the housing 10 are adapted in the illustrated embodiment in the area of the dial 35 to the outer contour of the dial.
a window 16 is also provided on the front side 11, through which a number 35 'or a symbol attached to the front side 36 of the number wheel can be read.
the locking gear 25, which is provided with evenly distributed circumferential recesses 26 and with locking cams 26 ', which have an arc-shaped flank profile 26 ", is preferably formed in one piece with the gear 30 and, as shown in more detail in FIG. 4, on an inside of the housing Sidewall 15 molded shoulder 18.
the gear wheel 30 is shown partially cut away in FIG. 1.
the digit wheel 35 which is rotatably mounted on the circuit board 65 about a pin 38, is operatively connected by an internal toothing 37 to the external toothing 31 of the toothed wheel 30, as shown in detail in FIG. 1.
each detent lever is fork-shaped for mounting a roller 45 or 55 which can be rotated about an axle pin 46 or 56.
the rollers 45 and 55 mounted on the detent levers 40 and 50 are pressed or pulled in a contacting manner by a tension spring 60 fastened to the detent levers in a manner not shown in the respective detent recess 26 of the detent wheel 25.
the coding rotary switch 1 is shown in view and the switching element 20, which is mounted on the side wall 15 and is provided, for example, with five switching fingers 21 and rotatable about an axle pin 27 in the direction of the arrow 2, can be seen, which corresponds to the switching fingers 21 with the detent cams 26 ' arranged and schematically shown ratchet wheel 25, the likewise schematically illustrated gear 30 and a portion of the circuit board 65.
FIG. 3 a part of the operating side of the rotary coding switch is shown in the front view according to FIG .
Fig. 4 shows the rotary encoder switch in section along the line IV-IV in Fig. 1 and one recognizes the housing 10, which is essentially box-shaped by the end face 11, the rear wall 12 and by the side wall 15, which on the side opposite the wall 15 in the is essentially closed by the circuit board 65.
the switching element 20 On the outside of the wall 15, the switching element 20 is arranged in a recess 9, which is non-rotatably connected to the journal 27 by a locking washer 28 in a manner not shown.
the ratchet wheel 25 resting on the shoulder 18 and the toothed wheel 30 are also connected in a manner not shown to the axle journal 27 rotatably mounted in the shoulder 18.
4 also shows the digit wheel 35 which is rotatably mounted with the axle pin 38 on the circuit board 65 and which engages with the internal toothing 37 with the external toothing 31 of the gear wheel 30.
a groove 19 is provided in a known manner on the outside of the wall 15, which, as shown in more detail in FIG. 2, runs essentially parallel to the recess 9, which is provided for the switching element 20 and is largely circular.
