BR-216, BR-220, BR-232 | Bistable relay • Bistable relays are used to switch electrical circuits by impulse command, especially for lighting control in ordinary houses, warehouses, production halls and other buildings. • Faster and easier installation thanks to an unlimited number of buttons, connected in parallel by two wires, which is a practical replacement for AC and cross switches. • Last but not least, they offer savings in the number of wires used and, in the case of the control circuit, the possibility of using wires with a smaller cross-section, where the power input is minimal compared to the power circuit. • The state of the Bistable relay changes with a short control pulse. As a result of which the relay in the steady state has zero consumption and is noiseless. • All relays can be controlled manually using a switch on the relay panel (I-O), which also serves as to signal the status of the contacts. • For types BR-220 and BR-232, it is possible to disconnect the electrical switch control and as a result the state of the relay can then only be changed manually (service, maintenance).
