A gap closing actuator (GCA) device (200) is provided. The GCA device includes at least one device drive comb structure (202a, 202b), at least one input/output (I/O) comb structure (216a, 216b) defining an output of the GCA device, and at least one device truss comb structure (204) interdigitating the device drive comb structure and the I/O comb structure, the truss comb structure configured to move along a first motion axis (205) between a plurality of interdigitated positions based on a first bias voltage (VBIAS) applied between the truss comb structure and the device drive comb structure. The GCA device also includes a brake portion (230) configured for selectively physically engaging the device truss comb structure to fix a position of the device truss comb structure along the first motion axis.
