Abstract

1,147,777. Retractive switches. ARROW ELECTRIC SWITCHES Ltd. 9 Aug., 1966 No. 35589/66. Heading H1N. A trigger-operated switch suitable for a portable power tool comprises a trigger having substantially parallel flat side parts with holes to accommodate pin-like projections of a support member received between said flat parts whereby the trigger is pivotally mounted on said support member. Both the trigger and support member are plastic mouldings and the pin-like projections are integral with the support member. The holes in the trigger may be elongated to facilitate fitting, or of triangular or other non-circular shape, and the pin-like projections may also be of non-circular crosssection, for example, polygonal.
