Abstract

519,605. Snap-action switches. SOLENTHALER, J. Jan. 26, 1939, No. 2691. Convention date, Jan. 26, 1938. [Class 38 (v)] Depression of a button 21 acts through a finger 19, resilient key 18 and roller 15<1> to depress an arm 5b of a three-armed lever 5 to turn a contact spindle 4, a snap-action being provided by a toggle spring 9. Spring 9 also acts through lever 8 and link 10 to press a roller 12 against a lever 16, and the tilting of lever 5 acts through link 13 to move roller 12 to the other side of the fixed pivot 16' of lever 16. Thus when the button 21 is released, lever 16 turns so that roller 15<1> moves on to arm 5a of lever 5. Thus a subsequent depression of button 21 restores the switch to the original position. A modified arrangement for moving the roller 15<1> across is also described. The button 21 may be dispensed with. In this case the lever 18 projects from the casing and is operated directly.
