10. Switch contacts

Mounting of switch contacts

First the snap t style bezel with sealing ring, and the gauge window, must be removed. Prior

to attaching the transparent hood to the measuring instrument, the contacts must be adjusted

in accordance with their operating range.

Using the magnetic snap-action contact, the magnetic retention force must be adapted to the

instrument-specic conditions by adjusting (twisting) the screw-in magnet. The magnet must

then be protected against unintentional adjustment by using an appropriate locking varnish.

The small plate spring at the exible contact arm must be angled accordingly.

The fully-adjusted unit must now be tted to the gauge, together with the snap-t bezel, and

aligned to the extent that the fork coupling guiding the exible contact arms grips over the

gauge pointer without touching the dial. Should this occur, the carrying fork must be shorte-

ned using a suitable cutting tool.

The contacts are best adjusted when they are factory-tted.

By snapping the bezel onto the case, the whole contact unit will be xed to the pressure

gauge.
