Abstract

963,091. Retractive switches. ILLINOIS TOOL WORKS Inc. Dec. 20, 1962 [Dee. 20, 1961], No. 48166/62. Heading H2B. A snap-action switch 10 comprises an insulating body 12 having a relatively rigid base portion 20 and an arm 28 integrally connected thereto by a flexible portion 32 and having a free end 30 movable in relation to the base portion to operate a flexible contact-carrying blade 14 with a snap-action. A central tongue 44 struck out from the blade 14 engages a groove 40 on the underside of arm 28 so that the torque is in compression and the spaced arms on either side thereof are in tension. Alternatively, the two outer arms engage notches in a raised portion of the base portion so as to be under compression and the free end of the arm maintains the central tongue in tension (Fig. 6, not shown). Blade 14 carries a contact 50 which snaps between fixed contacts 16, 18, which are metal stampings or printed contacts (Figs. 7, 8, not shown). There may be only one contact 16 or 18 such that the switch is normally open or normally closed.
