Abstract

607,501. Snap-action switches. SMART & BROWN (ENGINEERS), Ltd., SPIVEY, W. H., and STEVENS, B. Feb. 6, 1946, No. 3749. [Class 38 (v)] A snap-action switch comprises a slidable actuating member 5, a separate contact-member 8 in a recess 7 in the member 5, and a deadcentre snap-action mechanism, whose actuating part 23 is fitted with play between two walls 11, 12, of the member 8. When the member 5 is slid along the base it bears on the contactmember 8 which in turn bears on the part 23 until the dead-centre is reached, when the latter pushes the contact-member to the contact " make " or " break " position. The member 8 can pivot slightly about sides 9 in the recess 7 and is formed of a metal stamping, co-operating with contacts 15, 16. The deadcentre mechanism comprises rods 19, 20, pivoted at 21, 22 to the base and to the part 23, and surrounded by springs 17. A cover (not shown) retains the parts in position and prevents the entry of dust. The Provisional Specification also refers to Specification 585,310.
