ABSTRACT:
An electromagnetic relay has a normally-open contact tongue (2) with at least one finger (24a) which, during mounting, is first slidably engaged in a drawer-cavity-forming element (25). After adjusting a normally-open contact (3) relative to a movable switch-contact (4a) the position of the at least one finger is affixed in the drawer-cavity-forming element so that the position of the normally-open contact is fixed. The relay of this invention is characterized by having a particularly uncomplicated structure and by allowing a particularly uncomplicated, cost-effective, and fully-automated adjustment of the normally-open contact.
