Rugged,
weatherproof construction is a standard feature of JONES Heavy-Duty
Speed Switches. All rotating parts are mounted on factory-lubricated
ball bearings for smooth operation and exceptionally long
maintenance-free life. The three weight flyball governor is
the same as that which has made Jones the most respected and
trusted name in the heavy-duty tachometer field. These governors
have been proven in literally hundreds of thousands of tachometer
installations since their introduction by Jones in 1918.
