ABSTRACT:
A thermal limiter construction having a casing provided with an insulating end plug carrying a conductor with an enlarged contact head inside said casing and against which spring controlled sliding contact means in the casing normally engages to conductively interconnect the casing and the conductor together. A washer-like member is telescopically disposed about the contact head and is disposed between the sliding contact means and a spring that acts between the sliding contact means and the end plug to tend to move the sliding contact means away from the contact head whereby the washer-like member separates the spring from the sliding contact means. Such sliding contact means can comprise a plurality of conductive balls disposed in a circular array in the casing.
