Compact Button Cell Actuator:
Used to passively regulate a heat conduction path for temperature control.
Operation: Unit shown in its cold/retracted state. Upon heating the cell to within desired actuation range, the thermal wax changes phase, from solid to liquid, expanding in volume. The expansion is transferred via the flexible diaphragm barrier to the piston causing it to rise upward approximately 0.030” with a force capacity of up to 7 lbs.
