Switching on lights can lead to very high inrush

current peaks.

A closing contact can bounce 3 to 7 times until it has

closed completely. This creates a light arc which can

melt the contact surface. Micro-welding can take

place when the contact cools down (contact sticks).

To prevent sticking of the contact, relays with a

preceding tungsten contact are used.

Inrush current peaks for filament lamps of 165 A /

max. 20 ms, or for fluorescent lamps of 800 A / max.

200 µs can be switched with these.
