Specific embodiment

As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, a kind of motor DC switch, including including button 1, Pedestal, cover plate, are provided with wiring board 2, changement are provided with the pedestal on the cover plate, carry three on changement Station, i.e., left station, untransposition station and right working position.It is power transmission shaft 3 that the changement includes being fixed on pedestal, rotatable The moving block 7 being installed on power transmission shaft 3, the commutation that is rotatably installed on pedestal dial handle 6, the both sides difference of the moving block 7 Commutation shell fragment 8, i.e., left station shell fragment 8.1 and right working position shell fragment 8.2 are fixed with, are provided with the wiring board 2 and commutation shell fragment 8 The accessible commutation golden finger 9 for coordinating, handle 6 is dialled in described commutation to be included stirring handle 6.2, transmission handle 6.3, will stir 6.2 and of handle It is driven rotating shaft 6.1, the L-shaped STATEMENT OF FEDERALLY SPONSORED 15 being connected between transmission handle 6.3 and power transmission shaft 3 that handle 6.3 is connected, described transmission The elliptical drive groove 6.4 for coordinating linkage with L-shaped STATEMENT OF FEDERALLY SPONSORED L-shaped STATEMENT OF FEDERALLY SPONSORED 15, described elliptical drive groove are provided with the middle part of handle 6.3 6.4 extend along transmission handle length direction, and the commutation group handle 6 is realized rotating by rotating shaft 6.1 and installed, and by L-shaped STATEMENT OF FEDERALLY SPONSORED 15 and power transmission shaft 3 be connected driving moving block 7 rotate repeatedly, so as to change commutation shell fragment 8 with commutate golden finger 9 contact feelings Condition, realizes commutation.

The L-shaped STATEMENT OF FEDERALLY SPONSORED 15 of the present embodiment includes cylindrical shank portion 15.1 in slidable connection elliptical drive groove 6.4, connection Gangbar 15.2 between 3 end of cylindrical shank portion 15.1 and power transmission shaft, 15.2 integrally connected of cylindrical shank portion 15.1 and gangbar, The rotation of L-shaped STATEMENT OF FEDERALLY SPONSORED 15 drives power transmission shaft 3 to rotate, so as to the left and right for realizing moving block is beated.

On described changement also carry positioner, described positioner include one be installed on pedestal and with change The reset arc piece 10, button side that 6.3 free nose of handle is relative and establishing is closed is driven to group handle 6 to be provided with and commutation group handle 6 groups Two stopper slots 11 up and down that dynamic handle free end is engaged, by a grid spacer 12 with thickness between two stopper slots 11 It is separated by, dials pommel towards commutation in grid spacer 12 and coordinate with commutating to dial handle 6 and stir handle free end shape and be adapted.Grid spacer 12 effect not only causes the end positioning commutation when station is not commutated to dial handle 6 and stirs handle free end, supports in left or right station Gear commutation is dialled handle 6 and stirs handle side so that commutation group handle 6 is stirred handle free end and is limited in stopper slot 11.Described reset arc piece 10 is arch reset arc piece, and intermediate portion position indent 10.1 is that positioning commutation group handle 6 is driven 6.3 free nose of handle in untransposition work Position.

In untransposition station, as shown in Figure 3, Figure 4, commutation is dialled handle 6 to stir handle 6.2 push-jump to grid spacer 12, changes Move to handle 6 is dialled to pedestal direction, in elliptical drive groove 6.4, non-commutation side 6.41 compresses cylindrical shank portion 15.1, and drives ellipse Cylindrical shank portion 15.1 in driving groove 6.4 so that L-shaped STATEMENT OF FEDERALLY SPONSORED 15 drives moving block 7 to rotate so that 7 both sides of moving block are changed To shell fragment 8, i.e., left station shell fragment 8.1 and right working position shell fragment 8.2 are hanging, separate with commutation golden finger 9, correspondence, and do not commutate work Position does not have signal output.Group handle 6 that commutates simultaneously is stirred handle free end and coordinates spacing towards commutation group pommel with grid spacer 12, and In positioner, commutation group handle 6 is stirred handle free end and is positioned at recess in the centre of arch reset arc piece.

When left station is shifted to, as shown in Figure 5, Figure 6, it is push-jump to above grid spacer 12 that group handle 6 that commutates stirs handle 6.2 Spacing in stopper slot 11, commutation is dialled handle and is rotated, and in elliptical drive groove 6.4, commutation side 6.42 compresses cylindrical shank portion 15.1, drives ellipse Cylindrical shank portion 15.1 in circle driving groove 6.4, drives moving block 7 to rotate by L-shaped STATEMENT OF FEDERALLY SPONSORED 15 so that a left side for moving block 7 Station shell fragment 8.1 is contradicted with commutation golden finger 9, correspondence, left station signal output.Simultaneously in positioner, handle 6 groups is dialled in commutation Dynamic handle free end is butted on 10 bottom of arch reset arc piece, and spacing due to the arc active force of 10 bottom of arch reset arc piece.

When right working position is shifted to, as shown in Figure 7, Figure 8, it is push-jump to grid spacer 12 that commutation group handle 6 stirs handle 6.2 Stopper slot 11 in it is spacing, commutation dial handle rotate, in elliptical drive groove 6.4, commutation side 6.42 compresses cylindrical shank portion 15.1, drive Cylindrical shank portion 15.1 in elliptical drive groove 6.4, drives moving block 7 to rotate by L-shaped STATEMENT OF FEDERALLY SPONSORED 15 so that moving block 7 Right working position shell fragment 8.2 is contradicted with commutation golden finger 9, correspondence, right working position signal output.Simultaneously in positioner, handle 6 is dialled in commutation Stir handle free end and be butted on 10 top of arch reset arc piece, and limited due to the arc active force on 10 top of arch reset arc piece Position.

Although this utility model is disclosed as above with specific embodiment, but which is not limited to this utility model, appoints What those skilled in the art, in the case of without departing from spirit and scope of the present utility model, can still make a little change with Retouch, therefore protection domain of the present utility model should be defined depending on the defined person of the scope of appending claims.
