Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
118 words
A general purpose flasher device for automotive use and comprising: a relay having an armature connectable to two separate normally closed contacts and one normally open contact and a relay winding which when energized moves said armature to open said normally closed contacts and to close said normally open contact; a plus voltage terminal electrically connected to said armature; a normally closed load terminal connected to one of said normally closed relay contacts; a normally open load terminal connected to said normally open relay contact; a resistor and a condenser in series between said normally open terminal and the other of said normally closed relay contacts; and a thermistor in series with said ray winding across said condenser.
Claim 2
Dependent Claim
