Dual push-button code switches are connected with the name of Hartmann. We know what you are expecting and know our task and chance.

You will surely find the right product out of 10 different series in sizes from 15 x 6 mm to 32 x 11 mm with the choice of all the usual codes, 10- and 16 positions are available on most types.

With long-time tested materials we can achieve a high temperature resistance. Contact is achieved by gold on gold providing a low but consistant contact resistance.

Reliability is guaranteed by a solid design, assembly according to ISO 9001 and the electronic final test of every switch.
