Synchro-Start ESSD
The Synchro-Start Electronic Speed Switches were available in five variants: ESSB, ESSC, ESSD, ESSE-1 and ESSE-2.
The ESSD Speed Switch is the most compact, measuring less than 10 by 5 cm and ruggedly built to withstand tough applications. When actuated by a Mini-Gen Signal Generator; the switch will operate at speeds as low as 20 RPM.
Designed to provide overspeed or underspeed protection, crank disconnect, shift inhibiting on diesel engines and brake retarding on trucks and buses, the ESSD also has many other applications. For instance, it is being used as a safety device on buses to prevent doors from opening prematurely.
Although the ESSD is largely replaced by the Synchro-Start electronic or Woodward digital speed switches, some specific models of the ESSD are still available. We offer complete ESSD retrofit kits.
