Spaced transverseprtition plettes' l3 and t of insnleting materija'l are fitted within the cesing intermediate its ends, and are secured in pi ce by suitable ineans' suc es scrws IS. on the front face and near the edge of the rear partition 14 are secnre ii alplfirelity of paiis uo f spaced spring clip c'onttjcts, i' which are ar ranged in a circi ilers eries co I r'ic with the center of the' plate 14. Corresponding contact clips of certain ef the peirs of contact clips" ere connected in series withv ea'ch other as ett I '1 m Figure 7, and are agi l ted' to; be connected es at [3 to oneside of a sou 6 of current 19, the other spring clip contacts of said certie inpair's of con tact clips being also c'onnected' semester-1" each other as atZD in being adetnt'ed to he con nected to the other sid of said source of current as at 2 i through an aileirxn signed 22 and rounds 23 and 24, or the equ'iva'lent. one contectfclip at the point indicated sit (a inFi gur 7 of one of the remaining pairs of spring clip contacts is tIso connected to s n; one s'igepi the source of cur-L rent as at 25, and said" remeining peirs of spring l n t ed i edf 0 behl id'e to l ce them in series with each other etndfto close em ignition circuit when an of themjere bridged, For this purpose, the contact which is paired with the contact at a connected as at 26' with.

- another contacta't f; a-ndth'e contact etg which is paired with' the contact at ,f isconnected as at 29 with a wire 30 leading to the ignition coil of the automohile and having 1 single throw thtzrnh switch 3! intefposed therein. As shown in Figures 1-3 inclusive; the thumb switch 3| is 3 suitably mounted in a recess 32 provided in the lower portion of flange 9.
A plurality of pairs of spring clips 33 similar to the spring clip contacts I6, are similarly arranged with respect to and secured on the rear face of the front partition plate l3. Each partition plate has a circular series of openings as at 34, which are arranged so that one of the same is provided between the spring clip contacts of each pair and between the spring clips of each pair, each opening 34 of each plate being aligned with an opening of the other plate. Extending between and secured at their ends in aligned pair of the spring clips 33. Also, when the rods are moved forwardly, said other pin 3'! of each rod is received and held by a pair of the spring clips 33 and said one pin of the rod is disengaged from the pair of spring clip contacts l6.
A single unitary device is provided to select any desired ones of the rods and move them one at a time to shift their forward pins 3'! out of engagement with the spring clips 33 and to shift their rear pins 31 into bridging relation with the spring clip contacts Hi. This selecting and.
operating device is also adapted to similarly select the rods and move them one at the time to shift their rear pins 31 out of bridging relation to the spring clip contacts l6 and reset them with their front pins in engagement with the spring clips 33. This selecting and operating device includes a shaft 39 rotatably and slidably extended through central openings in the front end wall 6 of the casing and in the partition plates l3 and I4 as at 40, 4| and 42, respectively. This.
device also includes selector elements secured on the shaft 39 respectively in front of the front partition plate I3, and in back of the rear partition plate 14, each selector element comprising a plate 43 or 43 having a stud 44 or 44 projecting toward and selectively registerable with the adjacent ends of the rods. The rear end of the shaft 39 is received in a guide 45 carried by the rear end wall I, and helical compression springs 46 and 41 are disposed on the shaft 39, respectively between the front selector element and the front end wall 6 and between the rear selector element and the guide 45, to yieldingly oppose longitudinal movement of the shaft 39 in opposite directions and to normally position the selector elements out of engagement with the opposite ends of the rods 33. An indicator plate 48, provided with a central operating knob 49, is secured on the front projecting end of the shaft 39 so as to be normally positioned partly within the recess It! as shown in- Figure 3. On the margin of the indicator plate 48 is an index mark 59 which coacts with graduations provided on the adjacent face of the flange 9, the position of the index mark 5!] corresponding to that of the stud 44, and the positions of the graduations 5| corresponding to those of the rods 36.
In explaining the operation of the present switch, it will be assumed that the rods 36 are all shifted to their forward positions with their forward ends 3'! engaged with the front spring clips 33, and with the rear pins 3'! disengaged from the rear spring clip contacts 16. In order to close the ignition circuit, the thumb switch 3| is closed, and the indicator plate 48 is turned to register the index mark with graduation number 2 and thereby align the stud 44 with the rod numbered 2 in Figure '7. The shaft 39 is then pressed rearwardly to shift this rod 36 rearwardly and cause the rear pin 31 thereof to bridge the adjacent spring clip contacts l6 and to disengage its front pin 31 from the associated spring clips 33. This is also done successively with the rods numbered 5, 9 and I3, whereupon the ignition circuit is closed or completed. If any one of these rods are not so shifted, the circuit will notbe completely closed, and it will thus be apparent that an unauthorized person not familiar with the combination will have great difficulty in closing the ignition circuit and operating the automobile." Should any one of the remaining rods be so shifted, the circuit of the bination to close the ignition circuit without closing the alarm circuit. By changing the con-' nections with the spring clip contacts 16, the
combination may be changed, if desired. When parking in a public parking place, the present switch may be left in set condition with the ignition circuit closed through, the proper pairs of contacts i6, thereby permitting the attendant of the parking place to open and close the ignition circuit by mere operation of the thumb switch 3L. Any of the rods 36 which may have been shifted rearwardly may be readily retracted or reset to circuit opening position by aligning the stud 44' therewith and pulling the, shaft 39 forwardly.
From the foregoing description, it is believed that the construction, operation and advantages of the present invention will be readily under stood and appreciated by those skilled in the art.
Modifications and changes in detail of construction are contemplated, such as fairly fall within the spirit and scope of the invention as claimed.
Having described the invention, what is claimed as new is:
1. In a combination lock switch, an arcuate series of shiftable circuit-controlling members, a rotatably and slidably mounted actuator memher having spaced permanently and rigidly connected selective means .thereon respectively engageable with opposite ends of a single circuitcontrolling member for shifting the same when 2. The construction defined in "claim'i, where;
in each circuit-controlling member is provided with cross pins near opposite ends thereof, in
combination with a pair of spring clip contacts.

3. The construction defined in claim 1, wherein each circuit controlling member comprises a rod.
