ABSTRACT:
A step switch is formed by a rocking member which is coupled at its ends to perpendicular pivotting interlocking levers which, in turn, reciprocate a control plate in a longitudinal direction. The control plate carries pawls which engage ratchet teeth on a slidable contact holder to move the latter through one step in response to pressure on either end of the rocking member. A notch is formed for receiving each pawl at the end of its reciprocating path for preventing slip in the switch operation.
