Abstract
176,123. Comboni, G. Nov. 30, 1920. Switches, q u i c k - action; covers; contacts.-In a snap-action switch with a deadcentre spring action as described in Specification 138,866, the operating-lever 5, and the contact-lever 2 are both mounted on the same pivot 4 on a bridge-piece 7 secured to the base by fixing- screws 15, 16, one of which serves also as one of the terminals for securing one of the leads. A two-way form of switch is shown, but one of the fixed contacts may be dispensed with to constitute a single-way switch. The attachment points for the springs may be formed by stamped-up parts 10, 11 of the two levers and limiting-stops 18, 19 may be formed in the same way on the bridge-piece. The casing is in the nature of a cover and is secured by screws directly to a wall or base-plate.
