What is an ator relay?

Could you please elaborate on the concept of an ator relay? I'm curious to understand its function and significance within the broader context of electrical engineering or the specific application where it's commonly used. Is it a type of switch or relay that performs a unique task? And if so, what makes it distinct from other similar components? Additionally, are there any specific industries or systems that rely heavily on ator relays for their operation? I'm looking forward to gaining a clearer understanding of this intriguing technology.
