Definitions

  • the present invention relates to a mirror switch device according to the preamble portion of claim 1.
  • Figs.8 to 11 show a general mirror switch device 1.
  • an operating knob 2 is operated by pressing respectively upper, lower, right and left parts thereof .
  • a substantially rectangular plate shaped pusher 3 (see a two-dot chain line in Fig. 9 and a solid line in Fig. 11) is provided.
  • a pressure member unit 4 made of rubber is provided on the back surface side of the pusher 3.
  • six elastic pressure members 4a to 4f are formed by an integral molding.
  • a circuit board 5 is disposed.
  • switch parts 6A and 6F are arranged to respectively correspond to the elastic pressure members 4a to 4b.
  • the switch parts 6A to 6F have the same structures. For instance, one switch part 6C thereof is now described. As shown in Figs. 10 and 11, the switch part 6C comprises a movable contact 6Ca provided on the back surface of the elastic pressure member 4c and fixed contacts 6Cb and 6Cc provided on the circuit board 5.
  • the movable contact 6Ca In the switch part 6C, when the elastic pressure member 4c is pressed down, the movable contact 6Ca allows both the fixed contacts 6Cb and 6Cc to be electrically conducted (turned on) to each other. When the elastic pressure member 4c is returned, the movable contact 6Ca disconnects (turn off) both the fixed contacts 6Cb and 6Cc from each other.
  • the present invention has been invented by taking the above-described circumstances into consideration and it is an object to provide a mirror switch device having six switch parts in which two switch parts are turned on by selectively pressing and operating four side parts of a pusher to assuredly turn on the switch parts.
  • the invention provides a mirror switch device according to claim 1.
  • the one side part of the pusher has a total of three elastic pressure members located at two positions of both corner parts and one position between them correspondingly to the side part.
  • the elastic pressure members are located at the two positions of both the corner parts, even when one side part of the pusher is slightly slantingly pressed and operated or even when an eccentric position is pressed or operated, the two elastic pressure members located at both the corner parts corresponding to one side part are substantially equally pressed, so that the elastic pressure member between them is pressed. Consequently, the two elastic pressure members corresponding to switch parts are assuredly pressed to assuredly operate the above-described switch parts.
  • an operating force is more equally exerted on the three elastic pressure members corresponding to each side part, so that the switch operation is further assuredly carried out.
  • Fig. 2 shows a mirror switch device 13 viewed from a front.
  • a circuit board 15 is disposed in a switch case 14.
  • a pressure member unit 24 having eight elastic pressure members 16 to 23 is arranged on the circuit board 15.
  • the pressure member unit 24 is made of rubber and accordingly, the elastic pressure members 16 to 23 are also respectively made of rubber.
  • the eight elastic pressure members 16 to 23 respectively form a dome shape.
  • the elastic pressure member 23 as one of them will be described below.
  • This elastic pressure member 23 includes an operated part 23b at the top part of a thin rising part 23a.
  • the operated part 23b receives a pressure force in the direction shown by an arrow mark A in Fig. 3 to move toward the direction (see Fig. 6B), while the rising part 23a is deformed.
  • the operated part 23b is returned to an original position due to an elastic restoring force of the rising part 23a.
  • a pusher 26 pressed and operated by an operating knob 25 is provided in the side of operated parts 16b to 23b of the elastic pressure members 16 to 23.
  • This pusher 26 is configured in a substantially rectangular shape as shown by a two-dot chain line in Fig. 1.
  • the operating knob 25 is provided in the switch case 14 so that the respective side parts of upper, lower, right and left parts can be pressed and operated to prevent the operating knob 25 from slipping out by claw parts 25a.
  • pressure leg parts 25b are formed from the back surfaces of the four corners of the operating knob 25.
  • the end parts of the pressure leg parts abut on the pusher 26. Accordingly, the upper, lower, right and left sides of the pusher 26 are respectively pressed and operated in accordance with the pressing operation of the operating knob 25.
  • the pusher 26 and the operating knob 25 are returned to their original positions in accordance with the elastic reset operations of the elastic pressure members 16 to 23. Marks 25d, 25e, 25f and 25g showing operating points are formed on the operating knob 25.
  • a total of eight elastic pressure members 16 to 23 are provided respectively at the four corner parts (elastic pressure members 16, 18, 20 and 22) of the rectangular form of the pusher 26 and at four positions (elastic pressure members 17,19, 21 and 23) between them.
  • switch parts 27 to 32 are provided so as to only correspond to the two elastic pressure members 16 and 20 diagonally located at a pair of corner parts among the elastic pressure members 16 to 23, and the elastic pressure members 17, 23, 19 and 21 respectively located at both the adjacent positions to the corner parts. Since the switch parts 17 to 32 have the same structures, only the switch part 32 will be representatively described below.
  • the switch part 32 comprises a movable contact plate 32a attached to the back surface of the operated part 23b of the elastic pressure member 23, and fixed contact parts 32b and 32c opposed thereto and formed on the circuit board 15.
  • the movable contact plate 32a allows both the fixed contact parts 32b and 32c to be electrically connected and the switch part 32 to be turned on.
  • Movable contact plates 18c and 22c are formed (see Fig 4) on the back surfaces of the operated parts 18b and 22b of the other pair of elastic pressure members 18 and 22 which are located diagonally. However, fixed contacts opposed thereto are not formed and the switch parts are not substantially provided.
  • a reason why the elastic pressure members 18 and 22 are provided with the movable contact plates 18c and 22c (see Fig. 4) in a similar manner to those of other elastic pressure members 16, 17, 19, 20, 21 and 23 resides in that all the elastic pressure members have the same structures in order to facilitate a manufacture. In this case, the movable contact plates 18c and 22c may not be provided.
  • the elastic pressure members 17, 19, 21 and 23 between the corner parts are respectively provided at positions separated by equal distance from the corner parts (for instance, the elastic pressure member 17 is located at a position 1/2 as large as the clearance between the elastic pressure members 16 and 18).
  • the elastic pressure members 16 and 22 are provided correspondingly to the left side part of the pusher 26, especially at the two positions of both the corner parts, even when the left side part is slightly slantingly pressed and operated or an eccentric position is pressed or operated, the elastic pressure members 16 and 22 at the two positions of both the corner parts corresponding to the left side part are substantially equally pressed, andaccordingly, theelasticpressuremember23between them is likewise pressed. As a result, the two elastic pressure members 16 and 23 corresponding to the switch parts 27 and 32 are assuredly pressed to certainly operate the switch parts 27 and 32.
  • the elastic pressure member 23 between the corner parts of the elastic pressure members 16, 23 and 22 corresponding to the left side part of the pusher 26 is provided at a position equal distance spaced from the corner parts, an operating force is more equally exerted on the three elastic pressure members 16, 23 and 22 to more assuredly perform a switch operation.
  • the switch parts 27 to 32 may be composed of other switches such as tact switches.
  • the six switch parts are provided and the four side parts of the pusher are selectively pressed and operated to turn on the two switch parts, so that an excellent effect that the switch parts can be assuredly turn on can be achieved.
