ABSTRACT:
A magnetically actuated valve position sensing device for a linear or rotary valve comprising a switch housing completely enclosing one or more magnetic proximity switches. A mounting assembly comprises an outer housing for slideably receiving the switch housing, a magnetic rotary indicator on top the outer housing for indicating an open/close position for the valve and for actuating the switches in response to the shaft positions, and a shaft assembly for connecting the rotary indicator to the shaft of the rotary or linear valve. A bracket assembly mounts the switch housing to a stationary member of a linear valve and comprises brace members carrying magnets and connected to the linear valve shaft whereby the magnets actuate the switches upon translational movement of the brace members and the reciprocation of the linear shaft.
