    How to Use an Electromagnetic Relay on a Switch?

    Electromagnetic relay (EMR) is a kind of electrical relay that works in the effect of the suction between the magnet core and the armature in the input circuit. In other words, electromagnetic relay works in a way of driving the movable part in the magnetic circuit by the electromagnetic suction produced by the control current going through the coil, to achieve the function of contact open, closed and conversion.

    Today, we're gonna show you a type of electromagnetic relay ATO-MK2P-I.

    It features a quite strong. load capacity which is. 250V AC/10A, and its contact form is DPDT, which means Double Pole Double Throw.

    Given that, it can be used to trigger a signalor a contactor coil that comes with larger contact capacity.

    Looking through the transparent shell, You can see the relay has a visible contact on the inside that provides the relay with much stronger load capacity.

    The coil remains rated at 24V D.C, but what distinguishes it from Model HH52P is that it does not tell apart the positive and negative power poles as it has no LED indicators inside.

    On the whole, the size of ATO-MK2P-I is quite bigger than that of HH52P, while it's less complicated to wire MK than HH, because the former no longer uses the stepped wiring base.

    Similar to HH MK also has 35mm standard slots on the back of the mounting base. Then let's see how well it works.

    How electromagnetic relay work

    We are gonna connect 4 220V bulbs to the action terminal of the relay.

    Here is the circuit diagram.

    As is shown, No.1 and 4, No.5 and 8 are normally closed, and No.1 and 3, No.6 and 8 are normally open, No.2 and 7 are set for coil wiring.

    And we'll connect a push button to the circuit to control the close-and-open of the relay coil

    As the two sets of bulbs are controlled by separate circuits, you can switch on each set in turn by pressing the button, when L1 is disconnected, a pair of the bulbs will not be controlled.
