Abstract
The disclosure relates to a manually operated recodable coded switch in which a code may be inserted, tried and used to actuate a lever controlling an external device. After attempting a code, the switch's code wheels must be returned to their zero positions before another try is made.
Claims8
A coded mechanism comprising:
- a plurality of independently rotatable code wheel assemblies on a like plurality of generally parallel axes;
- means for rotatably supporting each of said assemblies on said axes, said code wheel assemblies being operably connected to a like plurality of independently rotatable code knobs for rotating said assemblies, each of said assemblies including a location at its periphery whose angular relationship is representative of a code bit;
- a control cam comprising a function cam and a function detent operably connected to a function knob, said control cam and said function knob having neutral, try, recode and actuate positions;
- and
- means controllable by said control cam for releasably engaging said code wheel assemblies, said assemblies being released for rotation at neutral, actuate and recode positions of said control cam, said try, recode and actuate positions being achievable only when said code wheel assemblies are rotated to positions where their angular relationships are representative of a correct code.
