MK-S General Purpose Relays

Omron MK-S General Purpose Relays are exceptionally reliable general purpose relays designed with a lockable test button. These relays feature an LED indicator, diode surge suppression, varistor, reverse polarity, and alternate wiring styles. The MK-S general purpose relays have built-in mechanical indicators that enable the checking of contact operation. For models with latching lever, two modes can be used for checking. These relays are ideal for operation checks in relay sequence circuits.
