ELECTRICAL SWITCH MECHANISM ABSTRACT An electrical switch mechanism which operates in response to predetermined deceleration and/or accel- eration is especially adopted for use on board trains for brake assurance purposes. Switch contacts biased to a safe switching condition are actuated by an arm. A pedulum pivots a predetermined distance with respect to the vertical. In response to a predetermined accelera- tion or deceleration, the arm is carried by the pendulum and may be mounted on a bracket plate such that the arm is set at a predetermined inclination with respect to the vertical. The arm actuates the switch contact only when the train reaches the predetermined acceleration or deceleration. The switch mechanism is vital in opera- tion in that the safe switching state is maintained in the absence of actuation. By adjustment of the bracket and arm inclination the mechanism can be set to respond to different selected accelerations and/or decelera- tions. Two sets of contacts biased in opposite direc- tions may be actuated by separate arms each carried by the pendulum. The mechanism is then responsive to deceleration in opposite directions is especially useful in trains which run in opposite directions without turn- ing around, such as subway trains. GRS - 458
