Abstract
An over-current and thermal protection device adaptable for use as an electrical interrupt and in a battery environment. The protection device has a pair electrical conductors, an electrically conductive resilient switch member engageable in contact with the conductors to define an electrical conductivity pathway. The switch member is actuated by a thermally responsive shape memory alloy strip and activatable in response to a change in temperature at a predetermined level to effect a change in the metallurgical state of the shape memory alloy and position of the engagement of the switch member with one of the conductors.
