Abstract

A miniature electromagnetic relay having a magnetic block and at least two sets of stationary electrical contacts. A moveable contact arm having a mounting end positioned in a base and two contact carrying portions extending from the mounting end. The improvement including a center tab portion on the moveable contact arm extending from the mounting end, between the extending contact carrying portions, and at a distance less than said contact carrying portions. The switching of the moveable arm from one set of electrical contacts to the opposite set being caused by the controlled energization of the magnetic block, which engages the tab of the moveable arm, causing closure of both contact carrying portions with the stationary electrical contacts at a lower electromagnetic force requirement and causing a more consistent relay operation.
