Abstract
An electrical slide switch includes a housing, first, second and third spaced, substantially aligned fixed contacts in the housing, a movable contact in the housing and a slide member which is operative for moving the movable contact between a first position wherein it is in engagement with the first and second fixed contacts and a second position wherein it is in engagement with the second and third fixed contacts. The movable contact is made from a resilient sheet metal, and it includes an elongated contacting portion having a central bump thereon and a pair of resileient biasing portions which are operative for biasing the contacting portion toward the fixed contacts. The biasing portions include inwardly extending portion which extend integrally inwardly from the ends of the contacting portion to spaced bends and outwardly extending portions which extend outwardly from the bends. The bump on the contacting portion engages the second fixed contact to cause the contacting portion to pivot as it is moved between the first and second positions thereof to provide a positive 'break-before-make' operation in the switch. The switch further includes detents which provide a crisp, positive snap-action in the operation of the slide member and alternatively position the slide member in the first or second positions thereof.
