Abstract

An electromagnetic relay for consumers with a high switch-on current peak has a main contact and a preliminary contact on legs which extend near one another. The legs carrying the main and preliminary contacts are connected at both sides with another leg via connecting webs and have each a stretch zone between a common connecting yoke of the legs and the connecting webs. At the stretch zones the main and preliminary contacts are adjusted independently of one another by means of squeezing the material of the contact carrier.
