Abstract
An electric switch is disclosed having a pivotal operating member which carries one contact and also includes biasing means to normally bias the switch to the "off" position.
Claims5
In a manually-manipulable, portable electric power tool, the combination comprising:
- a. a handle having an aperture formed therein;
- b. an electric switch housed completely within said handle, protected from external exposure, and having "on " and "off" positions;
- and
- c. a trigger member mounted within said handle, said trigger member being molded from a plastic material having high di-electric properties and a degree of inherent resiliency, and comprising:
- 1. pivoting means for mounting in recesses in said handle of said power tool;
- 2.
An electrical switch assembly for a power tool, comprising a trigger member formed from an electrically non-conductive material and adapted to be pivotally mounted in the housing of a tool for movement between a first and second position, the trigger member having a finger engaging portion adapted to project outwardly through an opening in the housing and an integral leg adapted to project inwardly, and having a first electrical contact mounted thereon whereby the contact will move in an arcuate pathway when the trigger member is pivoted between the first and second positions, a second electrical contact mounted in a fixed location within the housing in the path of the movement of the first contact such that pivotal movement of the trigger member to the second position operates to place the contacts in engagement to complete an electrical circuit.
