Abstract
Abstract A switch mechanism having an actuator or trigger supported to move within a housing between inner and outer positions corresponding to switch on and switch off conditions, separated electrical posts or terminals fixed on the housing spaced from but adjacent the trigger, and a single spring leaf element supported by the housing and urging the trigger to its outer switch off position, the spring leaf element having a detent portion that cooperates with an appropriate detent stop on the housing to releasably hold the trigger in said off position, and the spring leaf elements also having a contact spaced from the electrical terminals in the trigger off position but adapted to engage the terminals in the trigger on position for completing an electric circuit across the terminals.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
193 words
In an on-off switch mechanism, the combination comprising a housing, an actuating member mounted to move relative to the housing between spaced positions corresponding to on and off conditions respectively of the switch mechanism, a unitary resilient leaf element secured to the housing and having a spaced cantilevered portion operating against the actuating member and being operable with the resiliency thereof to bias the actuating member to the switch mechanism off position, said unitary leaf element having first and second cantilevered arms that are moved relative to the housing as the actuating member is shifted between its spaced operating positions, a pair of spaced terminals supported in the housing adjacent the first arm and an electrically conductive contact carried on the first arm disposed to be separated from the terminals when the actuating member is in the switch mechanism off position but disposed upon shifting the actuating member to the switch mechanism on position to be against both terminals, and cooperating detent means between the second cantilevered arm and housing engaged only when the actuating member is in the switch mechanism off position operable to releasibly hold the actuating member in said position.
Claim 2
Dependent Claim
193 words
In an on-off switch mechanism, the combination comprising a housing, an actuating member mounted to move relative to the housing between spaced positions corresponding to on and off conditions respectively of the switch mechanism, a unitary resilient leaf element secured to the housing and having a spaced cantilevered portion operating against the actuating member and being operable with the resiliency thereof to bias the actuating member to the switch mechanism off position, said unitary leaf element having first and second cantilevered arms that are moved relative to the housing as the actuating member is shifted between its spaced operating positions, a pair of spaced terminals supported in the housing adjacent the first arm and an electrically conductive contact carried on the first arm disposed to be separated from the terminals when the actuating member is in the switch mechanism off position but disposed upon shifting the actuating member to the switch mechanism on position to be against both terminals, and cooperating detent means between the second cantilevered arm and housing engaged only when the actuating member is in the switch mechanism off position operable to releasibly hold the actuating member in said position.
Claim 3
Dependent Claim
29 words
A switch mechanism combination according to claim 1, wherein the electrically conductive contact is formed on the free end of the first cantilevered arm integrally with said leaf element.
Claim 4
Dependent Claim
49 words
A switch mechanism combination according to claim 1, wherein the second cantilevered arm has a free end that is resiliently biased against the housing, and wherein the cooperating detent means is comprised of a tab on the free end of the arm and recess means therefor on the housing.
