The contact principle of this module is based on our assembled bolt contacts shown on pages 3/10 and 3/11 of this catalogue. Contact modules are suitable for transferring low current in narrow spaces or for use in equipments with manual operations. They are therefore quite often used as anode contacts as well. By combining a few of these modules, more current can be carried. The current transfer is done through the spring loaded contact bolts by means of a beryllium disk. The contact bolts can be exchanged from the outside. If desired, the modules can be assembled and mounted on Cu or MS bars for delivery.
