Abstract
The relay has a tube as coil/core carrier with end flanges, one flange being continued in a box like enclosure containing and pivoting the armature. Contact pieces reach into the enclosure, while a nose on the armature extends out of the enclosure for limiting the armature stroke and for actuating an auxiliary switch. A spring inside of the electromagnet bears against an armature plate which is pivoted on the yoke arm ends; the yoke is fastened to an exposed outer end of the magnet. The counter contacts are suspended by springs on the armature.

A relay with pivotable armature, an energizible coil, a magnetizable core, and means for changing the position of the armature when not attracted by the core, comprising:
- a tubular body, open at both ends and provided with first and second end flanges, the tubular body being the carrier for the coil and receiving the core;
- a top wall and two side walls integral therewith or connected thereto and extending from two opposite edges of the top wall at right angles, the top wall and the side walls extending from the first flange to define therewith a box-like enclosure having an open side opposite the first flange and an open bottom opposite the top wall;
- the top wall having at least one opening, there being a contact piece fastened to the top wall at the opening and projecting through the opening into the box-like enclosure;
- guide means at said side walls inside of said enclosure for pivotally supporting the armature;
- and
- a counter contact on the armature for making contact with said contact piece and receding from the contact piece upon actuation of said armature.
