SWITCH FOR DIRECTION INDICATORS Filed May 5, L931 M a xr-ronucv's Patented Mar. 21, 1933 UNITED STATES RINJIRO HADANO, OF HONOLULU, TERRITORY OF HAWAII SWITCH FOR DIRECTION INDICATORS Application filed May 5, 1931.

This invention relates to switches especially adapted for controlling direction indlcators and has for the primary object, the provision of a device of the above stated character whereby an electric circuit of a direction indicator may be easily and quickly controlled by the manipulation of a lever which is normally urged into an ofi or circuit breaking position and equipped with means for retaining the lever in circuit closing positlon until release of the lever for self-movement into circuit breaking position is desired.

A still further object of this invention is the provision of a switch for a direction indicator of the above stated character which will be simple, durable and efiicient and which may be manufactured and sold at a comparatively low cost.

With these and other objects in view, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which- Figure 1 is a horizontal sectional view illustrating a control switch constructed in accordance with my invention.

Figure 2 is a sectional view of the control switch taken at right angles to that shown by Figure 1.

Figure 3 is a transverse sectional view illustrating the electrically actuated means for releasing the switch lever from either of its signalling positions.

Referring in detail to the drawing, the numeral 5 indicates a conventional type of steering post of a motor vehicle and has secured thereto by a bracket a control switch 6 consisting of an elongated casing 24 having a switch lever 25 mounted therein and extending outwardly of said casing and equipped with a handle 26 located adjacent the steering wheel of the post 5 so that a person may easily actuate the lever without moving the hand from the steering wheel. The switch lever 25 is pivotally mounted intermediate its ends on a post 27 carried by the casing and Serial No. 535,231.

the free end of said lever is connected to a coil spring 28 which is in turn connected to the casing for the purpose of normally maintaining the lever in a neutral or circuit breaking position, as shown in full lines in Figure 1. Pairs of contacts 29 and 30 are supported by a suitable bridge 31 within the casing and located adjacent the inner end of the switch lever. movable contacts 32 and adapted to be alternatingly engaged with the pairs of contacts 29 and 30 when the switch lever 25 is moved into its dotted line position, as shown in Figure 1. The

movable contacts

32 and 33 are suitably insulated from the switch lever 25.

A bracket 34 is mounted in the casing 24 and has hinged thereto a locking plate 35, the free end of which is provided with relatively spaced notches 36 to receive a projection or lug 37 carried by the switch lever for holding the latter in any of its adjusted positions. A coil spring 38 is interposed between the bracket 34 and the locking plate for normally urging said plate towards the switch lever and will permit the lug 37 to ride into and out of the notches 36 during the movement of the switch lever when manually manipulated. However, the tension of the spring 38 is suiiicient to cause the locking plate 35 to hold the switch lever in any of its positions against accidental movement. Electromagnets 39 controlled in any suitable manner are mounted on the bracket and are electrically connected with one contact of each of the pair of contacts 29 and 30, as shown in Figure 1 so that when the switch lever 25 is in either of its circuit closing positions the electro-magnets are in circuit with the

contacts

32 and 33. The electro-magnets when energized are adapted to disengage the looking plate 35 from the switch lever 25 and permit the latter to return to a neutral or circuit breaking position by the influence of the spring 28. A finger piece 40 is carried by the locking plate 35 and extends through the casing 24 adjacent the handle 26 whereby a person may manually release the switch lever from either of its circuit closing positions.

While I have shown and described the pre- Said end of the switch lever carries ferred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope of my invention, as

claimed.

Having thus described my invention, what I claim is: p I

A switch comprising a casing, spaced resfl- 10 ient contacts mounted in the casing, a lever pivotally mounted in the casing with one end thereof arranged exteriorly of the casing to provide a handle and the other end of said lever arranged for movement between said contacts, resilient contacts carried by the lastnamed end of the lever to alternatingly engage the first-mentioned contacts during opposite movements of the lever by the handle, tension means connected to the lever and the p v 3 casing for normally positioning the lever to p i disengage the contacts, a spring pressed hinged latch. plate mounted in the casing and underlying the lever adjacent the handle and having spaced notches, a lug on said lever V V to engage in said notches for holding the lever i a a 2:. against self-movement and means for removing said plate to allow self-movement of the lever.

In testimony whereofI aflix my signature. 7 v- V, Y. 7 .2 v p RINJIRQ HADANO. i Y 53,-?
