ABSTRACT:
The disclosure relates to a manual switch having a lever positioned in opposition to a resilient coiled return spring anchored to a block which includes a projection engaging one of the coils of the return spring and thereby detaining either compaction or expansion of the spring until sufficient pivoting of the lever forces the detained coil to suddenly slidably traverse over the projection of the block to provide an audible noise and a tactile feel indicating sufficient pivoting of the lever.
