CS-1729 / CS-1429 / CS-1429-2

The CS-1729 has a Form 'C' relay. It can either be used as an Open circuit, Closed circuit or both. The CS-1429 can only be used as an Open Circuit and the CS-1429-2 is a Closed circuit. The 1429 series is less expensive because  the internal contacts are not as costly as a Form 'C' relay found in the CS-1729.
