Profile: Nolatron, Inc. is a manufacturer of anti-tiedown controls. Our anti-tiedown controls are used in conjunction with two start switches to require a machine operator to have both hands on the start switches in order to activate a machine cycle. The start switches must be released and then activated simultaneously to start the machine. Our 3380 series is designed for use with mechanical hand switches or self-checking electronic hand sensors. Our 4480 series is designed for use with single-pole hand sensing devices, such as optical hand sensing devices.
