. 9 Claims. (cl. zoose) This invention relates to an electric switch adapted to be mounted on a wall. While the switch is capable of use in various circuits for various uses, it is more particularly'designed for 5 the interior pf automobiles to control interior lights such as dome fights and the like. It is an object of'the invention to provide a small compact switch, the visible portions of ;which are an escutcheon and an. operating knob, both of in which can be made of molded plastic of any desired color. The switch elements are housed within these two members, the only external ele- 'ments being a pair of binding posts or the like which project from the rear face of the escutchl5 eon for electrical connections. 7 a
For a more complete understanding of the invention. reference may be had to. the foil'ow ing description of an embodiment thereof, and

a The switch illustrated on the drawing comprises an escutcheonplate III which may be of 35 any desired contour and of any suitable insulating material, preferably a moldable plastic. This plate is provided with suitable holes I! to receive screws by which it can be secured to a' supporting wall. Onthe-front face of the plate I- is 40 an operating knob 10 which is slidablethereon to open and close the switch. The knob 20 is-heid in assembled relation with the plate III by suitable means such as apair of posts 22 having heads embedded. in the knob 20. These posts 45 project rearwardly through corresponding slots 24 in." the plate-' .lll,-the slots being elongated in thesame direction so that the posts 22 can ride in the slots whenthe knobis moved from-one position to another. i As indicated in Figures 2 c and 6, each'of the slots 24 is enlarged near the rear face 'of the plate It, forming an inner shoul-- der 28; Seated against each shoulder 26 is a metal grommet ill which acts as a wear piece. The projecting end portions of the posts 22 are 55 expanded as at 32- after the posts have been inserted through the'narrow portions of the slots 24. The expanded end portions 32 overlap the wear pieces ll so that the knob is thus held in assembled relation with the plate It.
A pair of conductors ll are embedded in and 5 extend through the plate to, each of these conductors presenting its forward end face. for
contact with a brid conductor The bridging conductor may, as indicated in Figure 5, conslst of a strip of metal, the ends of which are bent up at right angles to the main portion of the conductor, the bent-up end portions 46 projecting into a pair of recesses 48 .formed in the rear face ofthe knob 20 when the same is molded.
'At the same time'a central recess so is formed in the knob between the recesses 48, these recesses being connected by a shallow channel 52 for the main portion of the bridging conductor M, The central recess 5| receives a compression spring 5|, one end of which is adapted to bear against the central portion of the bridging" conductor u when the end portions 46 are disposed within the end recesses l8. The member 44. is provided with a pair of small bulges 56 which are 'arranged'to make simultaneous contact with respective conductors 40. The forward end faces 42 of these conductors are preferably countersunk or hollowed as indicated in Figure 3, so
that ;the bulges 58 may ride into and out of these hollows, thus holding the switch yieldably in closed position. The spring 5| presses. the member 44 constantly toward the rear so thatthe bulges 56 are always -in firm contact withsome portion of the plate II or the forward ends 42 of the conductors l].
Projecting rearwardly from the back of the plate II are a pair of elements 60 which are by an end or the knob '20 when-the switch is open'and which is exposed when the knob is moved to close the switch.
