Push-button switch S comprises: a housing 1; A pair of fixed contact part 2 and 2 up and down is fixed in the housing 1; A pair of moving contact spare 3 and 3 up and down, they are worked with fixed contact part 2 and 2; A button 4 is used for operate mobile contact part 3 and 3; And a biasing spring 5, be used for biases button 4 on direction of retreat, and housing 1 usefulness screw 14 is fixed on the switch retainer D.
As shown in Fig. 2 to Fig. 6, housing 1 is made of a perimeter wall 6 and a rear wall 7, perimeter wall 6 is made of a upper wall 6a, lower wall 6b and a left side and right side wall 6c and 6c, and rear wall 7 integrally is connected on the rear end of perimeter wall 6, and open the front of housing 1.Dividing wall 8 rises from an inner surface of rear wall 7, and is connected to each other with a left side and right sidewall 6c and 6c, and dividing wall 8 is integrally formed in the housing 1, the internal insulation of housing 1 is become an epicoele 10 and a cavity of resorption 11.In at least one bottom surface of epicoele 10, that is, a middle body 12a of top surface 12 who makes dividing wall 8 is than the high step of opposite side of top surface 12, thereby if water enters in the epicoele 10, water can not remain on the middle body 12a yet.Lower wall 6b is equipped with a discharge orifice 13, is used for discharging the water that enters in the cavity of resorption 11.
Be provided with the projection 16 and 16 of a spring retaining hole 15 and a pair of vertical arrangement in a leading section office of dividing wall 8, spring retaining hole 15 is opened in the front surface of dividing wall 8, and between projection 16 and 16.
Fixed contact part 2 and 2 by plate shape contact portion 2a and 2a, and terminal part 2b and 2b constitute, terminal part 2b and 2b are with the crank shape bending, on the outer end that is connected to contact portion 2a and 2a, and fixed contact part 2 and 2 is installed on the rear wall 7 of housing 1, thereby its coupling part 2a and 2a are superimposed upon respectively on the top surface and basal surface of dividing wall 8.In this case, the contact portion 2a of top fixed contact part 2 is superimposed upon on the middle body 12a than the top surface 12 high steps of dividing wall 8 in particular.Thereby water can not rest on the contact portion 2a on the middle body 12a.
As shown in Figure 9, by being bonded on catching in the recessed portion 21 on the inner surface of installing hole 20 in the installing hole 20 that contact portion 2a is press fit into rear wall 7 places that are arranged on housing 1 and the pawl 22 of catching at the place, opposite side edge of contact portion 2a, said fixing contact part 2 and 2 is installed on the housing 1.
In Fig. 2 to 8, it is corresponding square with the perimeter wall 6 of housing 1 that button 4 forms cross sections, and four guiding supporting leg 4a are formed on the rearward end office of button 4, and these four guiding supporting leg 4a give prominence to from four bights on the glide direction of button 4.A locator protrusions 4b saliently is arranged on the top surface of its rear end part, and has it and face on the block pawl 4c of outer claw portion and the left side and right lateral surface that 4c is formed on rear end part (seeing Fig. 7 and 8 particularly).
Thereby, guiding supporting leg 4a and 4a ... be coupled to slidably in four bights of housing 1.Locator protrusions 4b is bonded in the location notch 27, and preventing the mistake assembling of button 4, location notch 27 is formed in the inner surface of upper wall 6a of housing 1. Block pawl 4c and 4c are inserted in blind hole 18 and 18, and blind hole 18 and 18 is formed on the left side and right side wall 6c and 6c of housing 1.Its claw portion is slidably engaged in from blind hole 18 and 18 towards the travel limits hole 19 and 19 that the outer surface of a left side and right side wall 6c and 6c is opened, thereby the inner front end of block pawl 4c and 4c adjacent rows degree drilling 19 and 19, the going-back position (see figure 7) of limit button 4 thus.
As clear expression in than 2 and 10, moving contact spare 3 and 3 is constructed by a kind of flat spring material monolithic ground.That is, form moving contact spare 3 and 3, extend back with upper and lower edge from a connecting plate 23.Arc-shaped contact part divides 3a and 3a to be formed on the respective rear ends place, and make its summit on direction away from each other facing to angular distortion part 3b and during 3b forms in the middle.Give moving contact spare 3 and 3 elasticity, with bias voltage on direction close to each other they.Simultaneously, a pair of prone installation sheet 23a and 23a are formed on a left side and the right side edge place of connecting plate 23.By installation sheet 23a and 23a being press fit in a pair of left side that forms at the place, rear surface of button 4 and right installing hole 24 and 24 and being bonded on each the catching in recessed portion 26 and 26 of inner surface of installing hole 24 at each the pawl 25 and 25 of catching at place, opposite side edge of installation sheet 23a, moving contact spare 3 and 3 is installed on the button 4.
Refer again to Fig. 3 to Fig. 6, moving contact spare 3 and 3 is contained in respectively in epicoele 10 and the cavity of resorption 11 in such a way, thereby moving contact spare 3 and 3 passes through from upper and lower pressure clamping dividing wall 8.
Thereby in the going-back position of button 4, the upper and lower projection 16 of dividing wall 8 and 16 engages with the fore-end of angular distortion part 3b and 3b, so that moving contact spare 3 separates with 2 with fixed contact part 2 with 3, thus push-button switch S is brought into disconnected state (see figure 3).When button 4 advances, projection 16 and 16 top side relative motions for angular distortion part 3b and 3b, and moving contact spare 3 is contacted with 2 pressure with fixed contact part 2 by its oneself elasticity with 3, thus push-button switch S is brought into logical state (seeing Fig. 4 and Fig. 5).In this case, the limit of advancing of button 4 is restricted (see figure 8) by connecting plate 23 in abutting connection with the front end of dividing wall 8.

In addition, owing to can be connected on the positive pole of battery 28 by water-immersed top fixed contact part 2 hardly, even, can prevent that also galvano-cautery from entering among fixed contact part 2 and the switch retainer D so the bottom fixed contact part 2 that is connected on the negative pole of battery 28 is under water with the bottom of switch retainer D.
When button 4 when the state of Fig. 3 moves to the state of Fig. 4, promptly when the biasing force that overcomes return spring 5 is pushed forward, the upper and lower projection 16 of dividing wall 8 and 16 is for angular distortion part 3b and 3b relative motion, and moving contact spare 3 is contacted with 2 pressure with fixed contact part 2 by its oneself elasticity with 3, to be electrically connected fixed contact part 2 and 2, thus push-button switch S is brought into logical state.Be advanced further at button 4 and arrive among Fig. 5 in the limit of advancing under the state, moving contact spare 3 and 3 contact portion 3a and 3a slide on the surface of fixed contact part 2 and 2.Therefore, a kind of like this wipe sliding effect can guarantee fixed contact part 2 and 2 with moving contact spare 3 and 3 between the best contact, thereby can operate electrical load 29 reliably.Label L in Fig. 5 represents the wiping trip slide of moving contact spare 3 and 3.
Even when the biasing force by return spring 5 makes button 4 when the limit of advancing retreats, contact portion 3a and 3a also slide on the surface of fixed contact part 2 and 2, separate with 2 with fixed contact part 2 with 16 by the projection 16 of dividing wall 8 with 3 up to moving contact spare 3, and therefore also can obtain wiping sliding effect here.
Secondly, will be explained in the second embodiment of the present invention of expression among Figure 11 to 13.
One second dividing wall 8 that is used for epicoele 10 is isolated into a left chamber 10a and a right chamber 10b is formed in the housing 1.Form each of basal surface of left chamber 10a and right chamber 10b, having two platforms, they be on the side of second dividing wall 8 upper brace 30a and on a left side or the lower platform 30b at place, the side of right side wall 6c.Being installed to an a pair of left side on the rear wall 7 and the contact portion 2a and the 2a of right fixed contact part 2 and 2 is placed on upper brace 30a and the 30a.An a pair of left side and right moving contact spare 3 and 3 are inserted among left chamber 10a and the right chamber 10b, and the disconnection and a closed a pair of left side and the right projection 16 and 16 that are used for controlling moving contact spare 3 and 3 are formed on the top surface of the fore-end of dividing wall 8 among left chamber 10a and the right chamber 10b.
Other element in this structure is identical with in first implements those, and by in Figure 11 to 13 identical label and allocation of symbols to being omitted its explanation with those corresponding elements in first embodiment.
According to second embodiment, pair of fixed contacts part 2 and 2 is arranged among left chamber 10a and the right chamber 10b, and left chamber 10a and right chamber 10b form by the epicoele 10 of isolating housing 1 by a little dividing wall 31.Therefore, water is difficult to enter left chamber 10a and right chamber 10b.In addition, fixed contact part 2 and 2 is isolated by little dividing wall 31, thereby improves water proofing property and electrocorrosion-resisting.
At last, will be explained in the third embodiment of the present invention of expression in Figure 14 and 15.
The 3rd embodiment has the structure identical with second embodiment, difference is, fixed contact part 2 and 2 is arranged in the top of a left side and right moving contact spare 3 and 3, and is used for according to moving forward and backward of button 4 moving contact spare 3 being installed on the upper wall 6a of housing 1 with an on/off control piece 32 that separates with 2 contacts with fixed contact part 2 with 3.Figure 14 with 15 in those corresponding elements in a second embodiment by identical label and symbol indication, and omit and explain.
