Abstract

667,350. Retractive switches; tumbler switches. MATHEWS, E. F. (Souza, M.O.). March 29, 1950. No. 7890/50. Class 38 (v). A changeover switch, e.g., for reversible electric motors, comprises an insulating body 1 having a through-slot 4 and two bores 10, 11 in which a conducting plunger 9 is slidable to engage either of fixed contacts 12, 13. A dolly 5 pivoted at 6 has forked ends 7 embracing the central reduced part 8 of the plunger, which is permanently, engaged by a spring-mounted contact 15. The plunger is normally retained in its central "off" position by a spring ball 24 engaging a recess 25 in the plunger, and is held in engagement with contact 12 by the ball 24 and a second recess 26, the plunger being returned automatically by a spring 27 from its right-hand "on" position. In modifications, Figs. 4, 5 (not shown), the plunger may be retractive from both "on" positions or held in both positions by the ball and recesses.
