Relay

With 3 contacts.

Stepping relays are used where consumers are to be switched on or off using a switch/button, e.g. work lights, seat valves, directional control valves, etc.Ie, if a current is applied to terminal 15 (button pressed once), the relay switches on terminal 87 and holds itself - current on terminal 87 despite releasing the button! When you press the button (impulse) again, the relay switches off again and terminal 87 is de-energized - impulse switch or toggle flip-flop.In the rest position of the relay, terminal 87a is constantly supplied with power and is in one Changeover function with terminal 87.Connections: 30 directly from the battery, continuous positive 87 consumer 1 87a consumer 2, constantly supplied with power over 30 when the relay is in the rest position 31 ground15 of switch/button, switching current 87, 87a changeover function (alternating current on 87 &~ 87a)

The switch-on relay separates the working current from the switching current. This means that large working currents can be switched with relatively small control circuit currents. There is no direct contact between the control and working groups. The controls and wiring can therefore be kept small in the control circuit.Connections:30 directly from the battery87 consumers87a Consumer 2, rest position, constantly supplied with power via 3085 Ground86 of switch, switching current87, 87a changeover function
