To all whom ill may concern:

Be it known that we, Jnnon PETER J'Aiion- SEN and HANS .Fnennim Jensen. subjects of the King of Denmark, both residing at Copenhagen, Denmark, have invented new and useful Improvements in Electric Switches, of which the following a spe ri-- ficetion.

The object of this invenl'ion is an electric switch or the like wherein a contact arm rotatable about the center of the loose in a plane parallel thereto is ope ated by means of a lever rotatable in a plane perpendicular to the plane of rotation of the contactarm, its inner free end acting on the contact arm through a helical spring or the like connectingpthese two members.

line invention is shown in the accompanyling iii ewings in which.

Flglllffi 1 shows a plain of the switch with the outer cover removed. Fig". 2 is :1 seeiion on the line lll lli oi? Fig: 1 Fig. 3 is e lsn View with the cover removed of (l nonlicelzion'of the invention, and is 22 section on the line il -IV of Fig. 3.

' Referring to the drawing 1 indiceles the socket, 2 the contact arm, 3, 3 the contact springs 4e, e the terminals, and '7 the SWllCll spring connecting ihe switch lever with one end of the contect arm.

The manner of execution shown in F 1-2 is erimigeias the ordinary iiiinhlei" switches, es for as the handle lever is concei'neol. This latter consists of a (lonble lever 13, is: extending through the cover and pivoted on e pin 15 having its hearings in :i

In the manner of execution shown in Figs.

Having now pziiiicnlei'ly described and sseeiileinecl the nature of one said invention end in what manner lheseine is to he performed, We l'leelei'e thee whet We claim is a plane perpendicular to the base, a spring connecting said contact arm to said tumbler lever and adapted to shift said arm from one position to another as said spring is actuated by said tumbler lever, for the purpose of opening or closing the switch.

. 2. An electric tumbler switch, comprising a contact arm, turnable parallel to the plane of the base; a tumbler lever, turnable in a,

plane perpendicular to the base, a spring connecting said contact arm to said tumbler lever and adapted to shift said arm from one position to another as said spring is actuatedby said tumbler lever, for the purpose of opening or closing the switch; said contact arm being retained in either of its signed our names in the presence of two sub- 20 scribing witnesses.
