This chapter discusses the operation of bistable relays. By bistable relays are meant relays whose armatures are magnetic, but which have only two positions and remain in the position they are in, until a new operation occurs. If, in the time interval N , no current has passed through the electromagnet coil, ξ = 0, then in the time interval N + 1, the contact remains in the same position as in the time interval N , x N +1 = x N . If, in the time interval N , the current has passed through the coil in the sense in which the armature is attracted, ξ N = 1, then in the following time interval, the contact is attracted, x N +1 = 1. The chapter also presents an analysis of networks with bistable relay. |
