The block is marked with 1,2,3,4. Seen from the beginning of the switch 1,2 is to the left and 3,4 to the right.
4 pcs of 2-core cables with female plug are jointed to 8- core cable with crimp connector. The core set is individually tested, 1500 VDC insulation test and continuity test, as well as visual and dimensional inspection to ensure void free moldings and a full bond onto the cable has been achieved.
After this, the core set are placed in a mould tool (4-way block) which is filled with Polyurethane/PUR, this is then cured in accordance with the manufacturers recommendations until full hardness is reached.
Final inspection is done and a final electrical test before it is packaged and dispatched.
