Abstract
A position limiting switch assembly is disclosed in this application for limiting movement of an associated device within limits defining a range of allowable movement and includes an input drive assembly responsive to movement of the associated device for driving a pair of counter assemblies each of which is in driving engagement with an actuator assembly. Each actuator assembly is positioned adjacent a switch assembly and when either of the counter assemblies reaches a position corresponding to a limit position of the associated device, the actuator assembly is driven to a position wherein its associated switch assembly connects a control circuit for the associated device. The corresponding positions of said counter assemblies are adjustable to accommodate various limit positions of the associated device.
Claims19
A position limiting switch assembly comprising counter means and input drive means operatively engaged therewith for driving said counter means in response to movement of an associated device, actuator means operatively engaged with said counter means for closing or opening associated switch means to or from adjustable limit positions, said counter means and said actuator means being relatively movable to a disengaged position whereby adjustment of said limit positions is facilitated.
A position limiting switch assembly comprising counter means and input drive means operatively engaged therewith for driving said counter means in response to movement of an associated device, actuator means operatively engaged with said counter means for closing or opening associated switch means in response to movement of said counter means to or from adjustable limit positions, said counter means and said input drive means being relatively movable to a disengaged position whereby the limit positions of said counter means can be adjusted.
A position limiting switch assembly comprising input drive means adapted to be driven by an associated device having first and second limit positions, first counter means adapted to have a first limit position corresponding to the first limit position of said associated device and second counter means adapted to have a second limit position corresponding to the second limit position of said associated device, said input drive means being operatively engaged with said first and second counter means for driving said counter means in opposite directions relative to each other whereby one of said counter means moves toward its limit position and the other of said counter means moves away from its limit position, first and second actuator means operatively engaged with said first and second counter means respectively, each of said actuator means being associated with switch means for actuating its associated switch means when its respective counter means reaches its limit position whereby a signal is provided that the associated device has reached a limit position.
