Abstract

1,138,418. Switch contacts. BAGH & CO. A.S. 13 June, 1967, No. 27222/67. Heading H1N. A switch comprises spaced fork-like contacts 1 electrically connectible by a pair of contact rails 2 mounted on a rectangular bolt 3 slideable in a slot 5 in a wedge 4. The wedge and rails are lowered between contacts 1 till the rails engage abutments (9, Fig. 1). Subsequent downward movement of wedge 4 relative to bolt 3 increases the contact pressure. The reverse occurs during switch opening. Rails 2 are urged by springs 6 towards wedge 4. There may be several bolts, and a cam on either side of wedge 4 may bear against the underside of rails 2 to raise them during switching-off. The wedge is moved by a snap-action mechanism (not shown).
