Abstract

Contact arrangement for electrical switching device and electromagnet and armature for alternately moving two switch arms into contact-making and contact-breaking positions. Two spaced contact springs insulated from each other are clamped in a switch housing. A stationary center contact is disposed between the contact springs and has a bifurcated contact end in the form of two legs, one bent tong-like toward one contact spring and the other bent tong-like toward the other contact spring. The two contact springs are biased to engage the stationary contacts and are operated to accommodate one contact spring to engage one stationary contact as the other contact spring is disengaged from the other stationary contact, by a card-like operating member of insulating material carried on the end of the armature. The operating member has a slot intermediate its ends through which one contact spring extends and forms a support at its end opposite the armature for the other contact spring.
