An illustrative example embodiment of an elevator brake control device (40) includes at least one primary switch (52; 54) configured to selectively conduct current for lifting all of a plurality of brake applicators (42; 44; 46; 48; 50). A plurality of secondary switches (62; 64; 66; 68; 70) are each associated with one of the brake applicators (42; 44; 46; 48; 50). Each of the secondary switches (62; 64; 66; 68; 70) is configured to selectively conduct current for lifting the associated one of the brake applicators (42; 44; 46; 48; 50). The plurality of secondary switches (62; 64; 66; 68; 70) are between the primary switch and the associated one of the brake applicators (42; 44; 46; 48; 50).
