Abstract
A visco-elastic actuator mechanism including a support section and an actuator section. A visco-elastic adhesive is mounted to one of the sections and is engageable by the other of the sections to hold the actuator in a first state. A spring urges apart one of the sections relative to the other until the actuator is abruptly switched to a second state.
