Installation Method of Tungsten Contacts in Automotive Relay

Installation method of tungsten contacts in automotive relay described below:

To maximize the performance of the automotive relay, the mounting direction should be consistent with the impact resistance direction of the automotive relay. That is, in order to effectively improve the anti-shock and impact resistance performance of the normally closed tungsten contacts in the non-energized state, impact direction should be perpendicular to the direction of movement of the armature and the tungsten contacts.

When it is installed, in order to improve contact reliability, the axial of tungsten contacts of automotive relay should parallel to the ground, to avoid spatter tungsten contacts, tungsten carbide falling on tungsten contacts surfaces.

If installing multiple sets of automotive relay, you should avoid large load tungsten contacts on the top of small load tungsten contacts.

If install large volume of relays, in order to prevent the mounting feet will damage in the condition of shock and vibration, you can choose housing mounting method.
