MK-S General-Purpose Relays

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