Abstract: A switch-over contact for relays or switches in which the contact forces can be easily, yet accurately adjusted without costly adjustment operations. According to the invention, the two contact arms of the switch-over contact have the form of an arc, i.e., they are elastically bent in the undeformed or unstressed state, but assume essentially the form of a straight line segment in the deformed or stressed state. The switch-over assembly comprises a pair of fixed contact members, and a pair of resilient contact arms, the fixed ends of the arms being mounted at substantially a common point in the device, the arms being bent to substantially a straight line positioning the free ends of the arms between the fixed contacts. An armature actuates to move the free ends of the arms into and out of contact with the fixed contact members.
