Bistable and memory relays - TOP

Bistable (or memory or pulse) relays are controlled by external buttons: press to turn on - press to turn off. They are used for push-button control of corridor and stair lighting as a replacement for AC (No. 6) and cross (No. 7) switches. The connection of the buttons is only on two wires in parallel - thus savings are achieved not only in the cables but also in installation, which is easy and fast.
