Sensing-SAF-Start, from JDS Products, prevents small machines from restarting after power interruption. After power has been restored, the unit will not reset until the machine switch has been turned off. Sensing-SAF-Start replaces the power cord on small machines such as table saws and drill presses, allowing them to conform to OSHA and NFPA safety standards by disconnecting machines' power during power loss. Available styles include one 240V and three 120V styles. All styles are UL-recognized.
