Installation direction

Installation direction

Unless otherwise specified, the installation direction of general relay is any direction, but in order to make the relay work more stable and reliable, the installation direction also needs good consideration.

1.1 Vibration and Shock Resistance

The ideal installation method is to make the action direction of the contact and the armature at right angles to the direction of vibration and impact. Especially when the coil is not energized, the normally closed contact has weak vibration resistance and impact resistance. If the installation direction is appropriate, its performance can be guaranteed, as shown in Figure below

1.2 Contact Reliability

During installation, the contact surface of the relay shall be vertical as much as possible, which can not only avoid the accumulation of garbage and dust, but also make the splashes and wear powder of the contact hard to attach to the contact in case of arc.
