Abstract
A manual switch for portable electric tools having minimum parts and ease of assembly. The switch is of the trigger actuated type and includes a single-piece molded housing, single-piece stationary contact-terminals, single-piece movable contact-terminals, and a snap-in assembled trigger. The double-pole stationary and movable contact-terminals are placed in slots in the single-piece molded housing member, this molded member is folded to form a switch housing, the return spring is inserted into the groove in the trigger, the cam end of the trigger along with the spring is inserted into the housing, the housing is closed by the rivet, and the trigger is snap-in assembled fully into its hole in the housing to complete assembly of the switch. The switch is connected to a tool motor circuit by pressing electrical conductors into holes in the bottom of the housing. These connections can be released by inserting a release tool alongside the lead, or by depressing built-in release buttons in an alternate design.
