ABSTRACT:
A crash-sensing switch assembly for breaking an electrical circuit has a weight pivotally supported on a horizontal surface with the center of gravity above the surface. The weight is free to move away from the surface if the assembly is inverted. Movement of the weight away from the surface, either by tilting or falling, brings the weight into engagement with the trip lever of a latch, releasing a switch to break the circuit.
