Filed April 9, 19 28 ZMM' gwvwntw Patented June 3, 1930 JOHN G. WOOD AND J OHN H. ALFES, OF LANSING, MICHIGAN, ASSIGNORS TO GENERAL MOTORS CORPORATION, OF DETROIT, MICHIGAN, A CORPORATION OF DELAWARE HORN BUTTON SWITCH Application filed April 9,
This invention relates to switch mechanism and particularly to switch mechanism such as that usually provided on the steering column of an automotive vehicle for controlling a signalling device.
The usual steering column of an automotive vehicle comprises one or more nested tubular shafts connected with the engine controls, each shaft having fixed to its upper end a control member provided with a handle. Usually the inner control member is recessed and carries in the recess the switch mechanism for actuating the signallingde' vice. The present invention relates to switch mechanism of this type.
In the usual construction a contact member is carried by a switch button mounted upon and engaging with switch mechanism held within the recess by means of screws or rivets. Considerable work is required in assembling this structure, and when the switch fails to make a good contact, due to the accumulation of dirt or for other reasons, the mechanism is with difficulty disassembled.
According to the present invention, I provide a switch mechanism which comprises separate members which are readily assembled in the recess and are held in position by a removable spring Wire clip. In the assembled switch the pa "ts are securely held in position so that no rattle can occur and yet may be easily removed or disassembled at any time it is desired to inspect the same.
In the drawing Fig. 1 is a plan view.
Fig. 2 is a section on the line 22 of Fig. 1.
Fig. 3 is a section on the line 3-3 of Fig. 2.
Fig. 4 is a section similar to Fig. 3, showing a modified form of my invention.
Fig. 5 is a perspective View of the control member.
The steering column comprises a tubular casing within which are nested the tubular control shafts. A steering wheel 14 is keyed to the outer shaft 12 and is fixed thereon by means of a nut 16. Within the steering shaft 12 is a tubular control shaft 18 on which is fined a control member 20 formed with a handle 22. Within the shaft 18 is an inner tubular control shaft 24 on which is fixed a 1228. Serial No. 268,612.
The control member 26 is formed with a recess 2'? in the bottom of which is an insulating plug 30 carrying a central terminal 32 to which is fixed an insulated conductor extending down through the shaft 24. A metallic washer 34 surrounds the plug 30 and contacts with the surface of the control member 26 within the recess.
Surrounding theplt'ig'30 and seating upon tl gwasher 34 is a spiral spring 35 on which seated, in normally spaced relation to the terminal 32,, a contact memben'iftlie form of a thin metal cap 36 formed with a central depression. Extending within the recess is a switch button 38 formed on its under side with a central boss 39 resting in the central depression in the contact member 36. The switch button is formed on its outer side with an annular groove 40 for a purpose described below.
The control member 26 is formed on oppo' site sides with slots 42 each of which receives an arm 43 of a U-shaped spring clip or clamp 44. The clip has bent ends 45 and is formed of spring wire which is normally held by its own tension with an arm in each slot 42, each arm extending within the recess and resting or the annular groove 40 on the outer side of the button. To remove the button, it is only necessary to spring one of the arms 43 out of its slot 42. All of the parts of the switch mechanism may then be removed. The width of the groove 40 is sufi'icient to permit the button to be depressed far enough to press the cap 06 into contact with the terminal 32,
thus ounding the terminal through the cap 36, coil spring 35, washer 34 and control member 26.
in the modification shown in Fig. 4, a controi mem er 26, corresponding to the control member 26, is formed with spaced openings 50 through which are extended the in-turned portions 54 of a plurality of arc-shaped wires 52, the inner ends of the portions 54 extending into the groove 40 on the switch button. in the embodiment disclosed, two wires 52 are provided, the openings 50 for the inturned portions being spaced at substantially equal intervals about the periphery of the control member. The wires are of material similar to the material in the clip a4; shown in the iirst three figures, and may be readily sprung out of and replaced in the position illustrated.
lVith the construction disclosed, the elements of tee switch mechanism are assembled separately in the recess in the control member and re securely held when the switch button is fixed in position. The switch button is iii-zed in position by a simple and inexpensive means which permits ready removal simply by springing the clip 44 (or one of the clips 52) outward. The spring clip is shown as comprising a wire, though any clip of this character which will remain on the control member with a portion extending within the recess for holding the switch button against removal may be used. The provision of the central boss on the under side of the switch button and the central depression in the contact member insures that the contact member will be centered at all times and will not becomeloese.
We claim: 1. In a switch mechanism comprising a mmmgrovided with a recess, a tubular member conncetedAvith said control member, an insulated conductor within said tubular member and having a terminal within said recess, a switch button extending within said recess and movable to and from a position grounding said terminal, means resiliently urging said switch button away from grounded position, and a retaining element on said control member and having a portion resiliently held within said recess for limiting the movement of said switch button.
