Since we started as Dongsung Electricity Co. we have produced Relay on OEM basis to supply to LS Industrial Systems and Honeywell Korea.
From 25 years of extensive work, we have accumulated differentiated know-how on Relay.

In June 2005, we acquired Miniature Relay RV and were able to transform ourselves into a company giving customers deep impression through strenuous improvement in product quality as well as in productivity.

Pursuant to the company objectives of guaranteeing product quality and maximizing product development capability, we will grow into a leading company in the production of Miniature Relay.

Now, we promise you all that D S Tech will be with you and value the market the most all the time.

We earnestly ask you to give us consistent interest and encouragement so that we can continue to develop our competitive advantage.
