Embodiment
Understand technology contents of the present invention for convenience of those skilled in the art, below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail.
As shown in the embodiment of Fig. 1-5, described sensitive switch comprises button 1, sealing ring 2, housing 3, spring 4, moving plate 5, rotor contact 6, pole 7, terminal contact 8, base 9 and terminal group 10, and each terminal group comprises public terminal, normally closed terminal and three terminals of normal beginning.Rotor contact 6 is riveted on moving plate 5 terminations.On base 9, one end is provided with two support columns 11, and the other end is established and kept out position 12, establishes Chang Kaiduan between the two.Pole 7 is placed on base, and one end is located between two support columns, and the other end props up keeps out position 12, has trepanning 71 and be placed on Chang Kaiduan by trepanning in the middle of pole 7; Moving plate 5 is positioned at the top of pole 7, and moving plate 5 is not riveted on one end of contact has furcation, and two furcations are connected to respectively on two support columns 11 of base.Normally closed terminal in terminal group 10 vertically through base keep out position 12, and top is bent to moving plate termination top.Moving plate and pole are caught on respectively in spring 4 two ends, and moving plate hooks hole 52,72 with upper corresponding being provided with of pole, and moving plate 5 is by the pulling force effect termination of spring 4 and the normal-closed end sub-connection of terminal group.When button is pressed down by external force, pole 7 take the position 12 of keeping out of base to be rotated for fulcrum, and the force direction of 4 pairs of moving plates 5 of spring changes, and makes the contact of moving plate 5 front ends leave normally closed terminal and contact with often opening terminal contact downwards, realizes circuit signal switching.
In described sensitive switch, button, sealing ring, spring, moving plate, rotor contact, pole, terminal contact, base and terminal group etc. are two, be each button, sealing ring, spring, moving plate, rotor contact, pole, terminal contact, base and terminal group independently signal switching mechanism and button mechanism of two of mix proportions respectively, the corresponding signal switching mechanism of each button mechanism.Two signal switching mechanisms cover in together in a housing and form a sensitive switch, and button is assembled on housing by sealing ring.During use, two cover signal switching mechanisms are connected in same circuit side by side, operate arbitrary button mechanism and make corresponding signal switching mechanism action realization that the signal in circuit is switched and all can.During use, can only operate one of them button, when one of them signal switching mechanism or button mechanism break down, can another corresponding switching mechanism be moved by operating another button, guarantee the normal work of circuit.Or operate two button mechanisms simultaneously two cover switching mechanisms are moved simultaneously, if one of them mechanism breaks down, another set of mechanism still can maintain the normal operation of circuit.
Because of in this sensitive switch, have two covers identical and independently switching mechanism be placed in same housing, by connecting terminals, access the uniqueness of output signal, so, when one of them switching mechanism of this sensitive switch was lost efficacy, and another switching mechanism still can work on, output signal is provided, to guarantee the integrality of switching function, reaches two-way safeguarding function.
In the present invention, button 1 employing metal headgear adds the form of plastic body, together with metal headgear 1 a is injection-moulded in plastic body 1b, to improve the resistance to wear of button.When this switch application door lock etc. is located, normally adopt cam-operated switch button, cam and button-shape are angled, and angle is larger, and button wearing and tearing are more serious, and metal headgear resistance to wear is good, so can be suitable for wide-angle operational applications.
Described housing is provided with the hole corresponding with sealing ring bottom shape 31, and Kong Zhoushe encloses edge, and sealing ring 2 encloses along being connected by rivet hot mode with hole, makes Wei Yan position, hole housing hot melt extruded sealing ring realize sealing.The corresponding sealing ring integrated injection molding of two button mechanisms, better tightness.
The position 12 of keeping out on base is provided with groove with the pole part that offsets; termination corresponding to pole is limited in groove and rotates in groove; middle part, termination corresponding to pole is provided with avoiding hollow groove 73, to avoid base, keeps out the die joint that position may exist and criticizes cutting edge of a knife or a sword, and assurance mechanism conversion is reliable and stable.
Above-described embodiment is only preferably implementation of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these apparent replacement forms all belong to protection scope of the present invention.
