    No, it is a relay

    A micro switch is never referred to as a relay nor is a torch trigger over here.

    So a voltage switch is referred to as a relay by you guys over there?

    Not really. A relay is sometimes referred to as a "electro-mechanical switch" but I've never heard of a switch being referred to as a relay and I've been design and building control systems and automation equipment for about 37 years, not that I couldn't have missed something.

    It is a micro switch and not a relay. A switch needs physical force to activate it. A relay has contacts like a switch but also a actuator such as an electrical solenoid to activate the switch and can be controlled remotely.
    Now put a solenoid on your switch and you have a relay.

    Nope the electrical portion of the Releco is a relay, the mechanical test push button is a switch.

    Same as a positioner table hitting an magnetic switch and reversing itself, no physical force really, just a polarity pickup, or even an electric eye picks up a discrepancy in its field of vision, or encoders that is also a switch for wave form production.
    An IGBT is a ultra fast switch, as are transistors, mosfets, scrs and such, all electrical switches.

    Its all the way you look at the problem to get the job done.

    Nope it is a relay, that is it's main function. Some relays have a mechanical actuator, "flag", led's whatever but for all intents and purposes they are still a relay with a coil and some contacts.

    IGBT's, fet's, micro's are indeed switches, they are not relays

    My main point is why do you guys refer to a micro switch or a trigger switch as relays?? This is the third time I have asked the question and all I get is a question in response to a question.

    Just curious as to why?

    Did you read my posts thats what I am asking, why would someone call a switch a relay ?

    I come from an aircraft background, circuit diagrams don't differentiate between a micro switch and a electromecanical relay. I know what thay are on a circuit diagram and that is all that matters. We were only talking about a foot pedal, where the OP was calling this device a limit switch.

    I called it a relay as 2 pins in the pedal close to tell the machine to start up.
    For me its symantics, I was trying to make it simple for the guy to understand

    Yes this is a mico switch even made by Mico switch
