Claim 5

Electrical protective apparatus as set forth in claim 3 in which the first leg is relatively stiff and the second leg is relatively flexible, said biasing means comprising a leaf spring that deflects said second leg toward said first leg when said one terminal is removed from between said first and second legs.

Claim 6

Electrical protective apparatus as set forth in claim 4 in which said first jaw member at one end thereof includes an outwardly extending ear to which said switch unit is mounted, said first jaw member having an outwardly extending first foot at the other end thereof, said second jaw member having an outwardly extending second foot resting on said first foot and secured thereto, said leaf spring having a foot at one end thereof and having the other end thereof bearing against the surface of said second leg remote from said first leg, said foot of said leaf spring resting on said first foot and secured thereto.

Claim 7

Electrical protective apparatus including first and second spaced mounting devices, a fused interrupter having terminals at opposite ends thereof removably held by said mounting devices; said first mounting device including first and second jaw members having respective first and second legs positioned in closely spaced relationship, biasing means urging said second leg toward said first leg to exert pressure clamping one of said terminals between said legs; a switch unit mounted on said first jaw member; said fused interrupter including a normally restrained striker pin that is released and ejected through an aperture in said one of said terminals when said fused interrupter blows; said switch unit including a contact actuator operatively positioned to be engaged and operated by said striker pin upon ejection thereof; said switch unit being repositionable with respect to said first mounting device to adjust the position of said contact actuator relative to said striker pin prior to ejection thereof; said first jaw member at one end thereof including an outwardly extending ear to which said sWitch unit is mounted.

Claim 8

Electrical protective apparatus including first and second spaced mounting devices, a fused interrupter having terminals at opposite ends thereof removably held by said mounting devices; said first mounting device including first and second jaw members having respective first and second legs positioned in closely spaced relationship, biasing means urging said second leg toward said first leg to exert pressure clamping one of said terminals between said legs; a switch unit mounted on said first jaw member; said fused interrupter including a normally restrained striker pin that is released and ejected through an aperture in said one of said terminals when said fused interrupter blows; said switch unit including a contact actuator operatively positioned to be engaged and operated by said striker pin upon ejection thereof; said switch unit being repositionable with respect to said first mounting device to adjust the position of said contact actuator relative to said striker pin prior to ejection thereof; said first jaw member at one end thereof including an outwardly extending ear to which said sWitch unit is mounted.

Claim 9

Electrical protective apparatus as set forth in claim 6 in which the switch unit is repositionably secured to said ear by a screw extending through an elongated slot.

Claim 10

Electrical protective apparatus including first and second spaced mounting devices, a fused interrupter having terminals at opposite ends thereof removably held by said mounting devices; said first mounting device including first and second jaw members having respective first and second legs positioned in closely spaced relationship, biasing means urging said second leg toward said first leg to exert pressure clamping one of said terminals between said legs; a switch unit mounted on said first jaw member; said fused interrupter including a normally restrained striker pin that is released and ejected through an aperture in said one of said terminals when said fused interrupter blows; said switch unit including a contact actuator operatively positioned to be engaged and operated by said striker pin upon ejection thereof; the surface of said first leg facing said second leg being provided with protrusion means for positioning a blade-type terminal relative to the actuator and a curved depression for positioning a cylindrical terminal relative to the actuator; said first leg being relatively stiff and the second leg being relatively flexible, said biasing means comprising a leaf spring that deflects said second leg toward said first leg when said one terminal is removed from between said first and second legs; said first jaw member at one end thereof including an outwardly extending ear to which said switch unit is mounted, said first jaw member having an outwardly extending first foot at the other end thereof, said second jaw member having an outwardly extending second foot resting on said first foot and secured thereto, said leaf spring havin a foot at one end thereof and having the other end thereof bearing against the surface of said second leg remote from said first leg, said foot of said leaf spring resting on said first foot and secured thereto.

Claim 11

Electrical protective apparatus including first and second spaced mounting devices, a fused interrupter having terminals at opposite ends thereof removably held by said mounting devices; said first mounting device including first and second jaw members having respective first and second legs positioned in closely spaced relationship, biasing means urging said second leg toward said first leg to exert pressure clamping one of said terminals between said legs; a switch unit mounted on said first jaw member; said fused interrupter including a normally restrained striker pin that is released and ejected through an aperture in said one of said terminals when said fused interrupter blows; said switch unit including a contact actuator operatively positioned to be engaged and operated by said striker pin upon ejection thereof; the surface of said first leg facing said second leg being provided with protrusion means for positioning a blade-type terminal relative to the actuator and a curved depression for positioning a cylindrical terminal relative to the actuator; said first leg being relatively stiff and the second leg being relatively flexible, said biasing means comprising a leaf spring that deflects said second leg toward said first leg when said one terminal is removed from between said first and second legs; said first jaw member at one end thereof including an outwardly extending ear to which said switch unit is mounted, said first jaw member having an outwardly extending first foot at the other end thereof, said second jaw member having an outwardly extending second foot resting on said first foot and secured thereto, said leaf spring havin a foot at one end thereof and having the other end thereof bearing against the surface of said second leg remote from said first leg, said foot of said leaf spring resting on said first foot and secured thereto.

Claim 12

Electrical protective apparatus as set forth in claim 8 in which the first foot includes protrusion means engaging said foot of said leaf spring at the free edge thereof to operatively position said leaf spring.

Claim 13

Electrical protective apparatus as set forth in claim 9 in which the switch unit is repositionably secured to said ear by a screw extending through an elongated slot in said ear of said first jaw member.
