Reversing switch actuator for fluid motor

A fluid motor having piston actuated switches on the cylinder heads thereof which control operation of a solenoid reversing valve to achieve automatic reciprocation of the piston. Each switch actuator comprises a radially positioned assembly which includes a relatively large diameter ball which is engaged by the piston as it approaches the end of its stroke, a large diameter spring follower which is spring biased against the ball, and a small diameter actuator rod which has sliding sealed engagement with a switch retainer in the cylinder head, the radially inner end portion of the rod being engaged with the spring follower and the radially outer end portion of the rod being engageable with the switch plunger to close the switch contacts to reverse the piston when the ball, follower, and rod have been moved radially outwardly by the engagement of the piston with the ball.
