Synchro-Start Mechanical Speed Switches

The Synchro-Start Mechanical Speed Switches an integrated speed sensor and switch. They come in four basic switch types: underspeed one element, overspeed one element, two element and three element.

There are eight different mounting styles available:

  • GO (SAE)
  • GH (Flexible cable)
  • GB (AND 20005 Tachometer)
  • GY (General Motors)
  • GW (General Motors Detroit Diesel)
  • GS
  • GR (Whitworth)
  • GJ (Metric M22 and M18 DIN75532)
  • Nowadays, most models are still in production and all mechanical speed switches can be made-to-order.

    Alternatively, as a retrofit solution, we offer upgrade packages to a Synchro-Start Mini-Gen (to replace GO, GW and GJ) in combination with an electronical or digital speed switch.

    If you have any other model than GO, GW, or GJ, we offer upgrade packages to magnetic pick-ups in combination with an electronical or digital speed switch.
