  • Mechanical AND-member for mutually locking power switches
    Patent number: 5892301
    Abstract: A mechanical AND element (U) serves for mutual locking of power switches (LS1, LS2, LS3). A carrier (T) serves as the stop for three flexible transmission members (S1, S2, S3) whose Bowden cables (S7, S8, S9) with parallel longitudinal axes act upon a coupling carriage (K). The Bowden cables (S7, S8) for the input signals (E1, E2) work in opposite directions and are engaged with the coupling carriage (K) at the outside and approximately in the center, respectively. The Bowden cable (S9) for the output signal (A) is connected to the other, outer, side of the coupling carriage (K).
