Abstract
A power switch device has a housing, a movable shuttle and at least one shape memory alloy actuator. The housing has a cavity and stationary current carrying contacts which extend through the housing to the cavity. The movable shuttle with a bridge contact provided in the cavity. The at least one shape memory alloy actuator is attached to a first end of the shuttle and to a first end of the housing. The at least one shape memory alloy actuator is configured to respond to a first activation signal. The at least one shape memory alloy actuator contracts from an initial shape in response to the first actuation signal to move the shuttle and the bridge contact toward the stationary current carrying contacts to a closed position in which the bridge contact is positioned in electrical engagement with the stationary current carrying contacts.
