Abstract

An apparatus for moving a pair of opposing surfaces in response to an electrical activation having a support including a rigid non-flexing portion (16), at least one pivotable arm portion (18, 20) extending from the rigid non-flexing portion, a pair of opposing surfaces with one opposing surface (22, 24) on the at least one pivotable arm portion (18, 20) for movement relative to one another, and a force transfer member (26) operably positioned for driving the at least one pivotable arm portion in rotational movement. An actuator (14) is operably engaged between the rigid portion (16) and the force transfer member (26) to drive the force transfer member in movement relative to the rigid portion to pivot the at least one pivotable arm portion in response to an electrical activation of the actuator.
