ELECTRIC STARTING-MOTOR SWITCH.
Application filed February South Orange, in the county of Essex, State 1 of New Jersey, have invented certain new and useful'lmprovements in Electric Starting-Motor Switches, of which the following reference being had to the accompanying drawing, and to the figures of reference marked thereon.
' 'This invention relates to an electrical switch particularly adapted for use in connection with an electric starting motor used on internal combustion engines in automofive vehicles, although, it is to be understood that the switch is adapted for other uses where an electric circuit is to-be controlled. It is the principal object of my invention to provide a switch that will make and keep a large contact area and good electrical contactduring the period of time that the electrical circuit is closed through the switch.
Another object of my invention is to provide a switch that is sturdy and rugged and one that will therefore, stand a lot of abuse, at the same time.
A further object is to provide a switch that is cheap and economical-to manufacture.
,These and other objects will be apparentfrom a study of the drawing taken in connection with the specification in which Figure 1 is an elevati-onal view, partly in section, of the switch.
' Figure 2 1s a new of the bottom part of the cover showing the movable switch memher in position.
Figure 3 1s a plan view looking down on vthe box portion of the switch showing the stationary contacts in position.
Figure 4 is the bottom view of the cover, but with the movable, switch member removed.
Figure 5 is a perspective view of the guiding member used in connection with the movable switch member.
Referring now to the details wherein like 7 numbers refer to corresponding parts in the various views, 1 is the body or box portion of the switch havingestationary contacts 2 and 3 mounted therein but insulated therefrom. The contacts 2 and 3 are preferably of copper and terminate in threaded ends on the exterior of the box; nuts 4 being provided for locking the terminals in position.

purpose which will be more clearly understood on reading the description of the movable contact member. The box 1 has a flange 5-with mounting holes 6 therein. Fitted to the flange 5 is a cover 7 having a plurality of cars or projections 8, four being indicated, which are adapted to be bent over the flange 5 to hold the cover in position on the box portion of the switch. To the cover 7 is attached a stem 9, the same being held thereto by a plurality of fingers 10 which are riveted or clenched over within a slightly upward depressed portion 11 in the cover. The cover is also provided with a pair of slots 12 that open through the cover within the interior of the stem 9. These slotsv 12 are for the purpose of receiving the fingers 13 on the guide member 14: which has a hole 15 to receive preferably a shouldered end of the plunger 16 carried within the stem 9 and provided with a cap 17 which is preferably fastened securely to the upper end of the plunger. A spring 18 serves to hold the plunger in retracted position as shown in Fig. 1. Positioned on the inner end of the plunger and adj acentthe guide member 14, is a spring contact member 19; A suitable insulator or insulator 20 acts to insulate the spring contact member 19 from the guide member 14 and the plunger 16. The insulators are also constructed so that the projections 21 of the guide member will not come in contact with the sides of the spring member 19, but engage the insulator 20 so as to prevent the spring contact member 19 from turning on the plunger 16 and the plunger itself is prevented from turning through the cooperationof the fingers 13 and the slots 12. The spring member 19 is preferably constructed of a plurality of leaves which may be of diiferent material. However, the leaf that engages the contacts 2 and 3 I preferably make of copper and at- I tach the extreme end thereof to the other leaf or leaves by bending the end 22 over the other leaf or leaves, preferably in a slot 23-provided in the other leaf or leaves. The contact member 19 has a straight portion as shown in Fig. 1 against which, the insulator 24L rests on one side and the insulator 20 and the plunger 16 being preferably rivetedover .a
