- Each connecting portion 93, 93' is for example part of a corresponding electrical connecting terminal C2, C3 of the switch 10.
- Each connecting terminal C2, C3 include a screw 94, 94' and a clamping plate 95, 95' and each screw 94, 94' crosses the respective connecting portion 93, 93' for engaging with an associated clamping plate 95, 95'.
- the mobile electric contact elements 82, 82' are for example two opposite electrically conductive pads, e.g. made of sintered silver, fixed, e.g. welded, at the opposite sides of an end portion of a mobile contact element 81, also made of electrically conductive material, e.g. copper. It is thus clear that in this embodiment the mobile electrical contact elements 82, 82' are electrically connected between them.
- the opposite end portion of the mobile contact support 81 lies on the supporting fulcrum 50 and in particular on the portion and support and contact 51 of the supporting fulcrum 50.
- the mobile contact holder support 81 rotates around a first rotation axis A3-A3, in the example defined by the supporting fulcrum 50, in order to rotate the mobile electrical contact element 82,82' between the first and the second operative portion and vice versa.
- the mobile contact holder support 81 is an L-shaped plate having a larger base 810 lying on the supporting fulcrum 50 and a more narrow arm 811 of the base 810 that protrudes from the base 810 and on whose end portion opposite to the base 810 the mobile electrical contact elements 82,82' are fixed.
- the rocking control member 70 includes a body 75, preferably made of electrically insulating material, e.g. plastic, rotatable with respect to the case 20 to rotate around a rotation axis A2-A2 (herein called second rotation axis too) , parallel to a first rotation axis AB ⁇ AS, in order to rotate the rotatable contact holder support 81.
- a rotation axis A2-A2 (herein called second rotation axis too) , parallel to a first rotation axis AB ⁇ AS, in order to rotate the rotatable contact holder support 81.
- the second rotation axis A2-A2 is parallel both to the third rotation axis Al-Al and to the first rotation axis A3-A3.
- the body 75 of the rocking control member 70 is rotatably hinged to the case 20.
- the body 75 of the rocking control member 70 is shaped in such a way that the rotatable contact holder support 81 in the rotation around the first rotation axis A3-A3 can cross the second rotation axis A2-A2, that is the rotation axis of the body 75 of the rocking control member 70.
- the body 75 of the rocking control member 70 includes a contact portion 72 having two shaped surfaces 701, 702 intended to be alternatively contacted and pushed by the pressure transmitting member 60, and in particular by the two appendices 601,602.
- the two shaped surfaces 701, 702 are two stepped surfaces.
- the body 75 of the rocking control member 70 includes a bridge portion 71 bypassing an operative space 710 in which the rotatable contact holder support 81, or an end portion thereof, as for example an end portion of the arm 811 is free to rotate.
- the bridge portion 71 includes at least a bended bridge arm 711, 712, 713, preferably two bended bridge arms 711, 713 originating from two different points of the body 75 and joining in the same point.
- the bridge portion 71 includes three bended bridge arms 711, 712, 713 originating from three different points of the body 75 and joining in the same point to form a cage structure that defines the operative area 710 within which the rotatable contact holder support 81, or an end portion thereof, as for example an end portion of the arm 811, is free to rotate.
- the bridge portion 71 may include a continuous bridge wall provided with a recess or a pocket within which the rotatable contact holder support 81, or an end portion thereof, is free to rotate.
- the bridge portion 71 also bypasses a space occupied by the fixed contact holder support 91, 91', by the fixed electrical contact element 92, 92' and by the mobile electrical contact element 82, 82'. In such a way the bridge portion 71 bypasses a space region of the switch 10 wherein the joining and separation between the mobile electrical contact element 82, 82' and the fixed electrical contact element 92, 92' occurs.
- the switching control member 70 includes two opposite coupling elements that allow the rotatably coupling of the control member 70 with two opposite lateral walls of the case 20.
- the aforesaid coupling elements include two opposite cylindrical shaped pins 76 protruding from the body 75 along the rotation axis A2-A2 in opposite directions.
- one of the aforesaid pins 76 protrudes from the contact portion 72 and the other of the said pins protrudes from the bridge portion 71.
- such pins 76 are inserted in corresponding pass- through holes or recesses 276 defined in two opposite lateral walls of the case 20.
- the body 75 of the rocking control member 70 includes a portion 73 containing an internally hollow seat adapted to receive an elastic element, e.g. a coil spring 77, operatively inserted between the rocking control member 70 and the mobile contact holder support 81.
- an elastic element e.g. a coil spring 77
- a wall 79 with a recess (not visible in the drawings because it points the bottom wall 21 of the case 20) adapted to receive an end of an elastic element (as for example a coil spring) adapted to make the rocking control member 70 a monostable member.
- the proposed push button operated switch 10 allows to fully achieve the planned scopes in terms of overcoming the drawbacks of the prior art.
- experimental evidence has demonstrated that, thanks to the provision of a system of spatially distributed guides including first guide elements 22, 32 operatively interposed between the lateral walls of the push button 30 and the lateral walls of the case 20 and second guide elements 23, 24, 33, 24 spaced apart from the first guide elements 22, 32 and arranged with respect to the first guide elements 22, 32 at a lower distance from the bottom wall 21, it is possible to significantly reduce the friction surfaces between the push button 30 and the case 20, limit the vulnerability of the switch 10 with respect to dust or sand insertion and keep contained the axial encumbrance of the switch.
