A magnetic joy stick and stack valve remote control structure comprising a housing having inlet and outlet chambers separated by a common inner wall, an inlet port in the housing communicating with the inlet chamber, an outlet port in the housing communicating with the outlet chamber, at least one control valve port in the housing communicating with the inlet chamber, a valve member slidable in said control valve port and connecting the control valve port with the inlet chamber in a first position and with the outlet chamber in a second position, a resiliently biased valve operator normally holding the valve in the second position, a joy stick pivoted on the housing to engage said valve operator to move the valve between the first and second position, a magnetic coil adjacent the valve operator, a detent pin movable centrally in said coil, means at one end of said detent pin for holding said valve operator in the said first position, a coil plate on said coil in contact with the detent pin opposite said means for holding the valve operator in the first position, and resilient means urging said coil plate toward the coil whereby the coil plate is in constant contact with the coil except when the detent pin forces the coil plate away from the coil when the joy stick is moved to operate the valve from one of said first and second positions to the other of said positions.
