Abstract
831,539. Snap-action switches. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. June 14, 1956 [June 15, 1955], No. 18431/56. Class 38(5). A switch comprises an actuating lever 1 pivoted at 5 and connected at one end to a link 11 carrying a spring 2 and having a pin-and-slot connection to a contact lever 3 pivoted at 10. The lever 1 carries stops 6, 6a which in the respective end positions bear on the lever 3 to increase the contact pressure and which also give positive actuation. In another form, Fig. 2, the lever 1 is in two parts, the part 9 carrying the stops 6, 6a. In Fig. 3, the lever 1 has projections 6b, 6b<SP>1</SP> which co-operate with the respective arms of a two-armed lever 3. The contacts 4 may be carried by a rectilinear slider 13, Fig. 4a, the lever 1 in each end position bearing against a lever 21a or 21b, which respectively give positive actuation and increased contact pressure.
