Description

Patented Sept. 6, 1938 UNITED STATES SWITCH William H. Frank and Lawrence E. Fisher, Detroit, Mich.
Application January 16, 1936, Serial No. 59,379
18 Claims.
This application relates to contact arrangements for switches and more specifically relates to multiple break contact arrangements.
For an understanding of the switch contact arrangements herein, disclosed reference should be had to the appended drawing disclosing the same. 1
In this drawing, Figs. 1 and 2 are sections as if on line I-l of Fig. 3 showing the switch parts in on and off positions respectively.
Fig. 3 is a side elevation.
It will be seen that the contact arrangement herein disclosed includes an insulating base l0 upon which are mounted spaced stationary contacts II having conductor terminal binding posts l2. For engaging each of the stationary contacts there is provided, within a slide 15 formed as part of an insulation housing IS, a movable contact 35 formed to engage the contacts with a butt pressure and with a wiping contact engagement.
In addition the housing I6 is shown as provided with a U-shaped contact spring 35 having contact tips 31. The spring 36 functions to urge the tips of the stationary contacts ll towards each other and thus increase the butt contact pressure of them on contact 35 and to urge contact tips 31 tightly into engagement with the stationary contacts ll; contact tips 31 provide arcing tips: it being observed that contacts 31 make with stationary contacts ll before and break therefrom after the movable contact 35 makes and breaks contact with contacts I I.
The housing It is adapted to be reciprocated by means not shown for make and break.
35 It will be observed that the edges of the openings in the bottom wall of the housing IS on the opposite sides of the blade l5 through which contacts ll pass are dimensioned'to fitclosely 40 around the stationary contacts ll so that the interior of the housing is sealed at alltimes by the stationary contacts ll.
Now having described the switching contact arrangement herein disclosed, reference will be had to the following claims for a determination of the inventions claimed.
