摘要： A quick stop circuit for a spring applied quick stop mechanism coupled to an electrically operated actuator includes a dual quick stop switch which includes a simultaneously operated normally open switch and a normally closed switch. The closing of the normally open switch causes control units to turn off a relay which controls energizing of the actuator through an actuator relay. The opening of the normally closed switch de-energizes a quick stop relay which disconnects the driver from its power source, which also de-energizes the actuator relay, which de-energizes the actuator so that the spring applied quick stop mechanism will move to its stop position.
