Hello dear team, I would like to add an Emergency Stop Push Button Switch to a light that use LED COBs.
I know Emergency Stop Push Button Switch are supposed to work in "commutation" with a relay.
But in my case I would to simplify the installation. According to the specs of this Stop Button and my electric current, is it safe?

I want my circuit will use a 6 ampères / 220 volts current.

The Stop Button is a 1NC SPST: ( a single normally closed (NC) contact and is a single pole single throw (SPST) type. This means that the contact is closed when the push button is not pressed and opens when the push button is pressed.)

Action Type: Latching: This indicates that the switch has a latching mechanism that prevents the push button from accidentally tripping.

10A : the rated current capacity of the switch

440V: the maximum rated voltage for the switch,

6KV: the rated impulse withstand voltage

AC15: 240V 3A: The switch is able to switch an AC15 load of 240V/3A.

Quantity of terminals: 2

Also if I use the Button stop in a connection in series, that means that it will receive a 6 ampères / 220 volts current that is lower than the rated current and maximum rated voltage. Also, that means that it will work safely although this doesn't use any relay?

Or will I burn ?

Best regards

Jonathan

 

If your circuit takes 6amps and the switch is rated for 10a, then it is within the operating range of the switch.
One of the reasons for using a relay is that more than one circuit can be switched by the E-Stop.

 

Ok, thanks a lot a lot for your quick answer. That's great. Thanks

 

Do you want the stop action to remain after you release the button?
If the button doesn't do that, then you will need to add a relay to give a latching function.

It appears from the TS that the switch is already latching, although his description is confusing because he describes the “latching mechanism” differently than what one would interpret that function. I wouldn’t think preventing accidental triggering to be a latching type. To be sure, s/he should provide a link to the exact switch planned to be used.

 

One common version of the E-stop push button, is the latching type, where normally you would use a pull action to turn it off, but there is also some that are push-latch-on, Push-return-off .
but these are typically rarer for E-stop functions.

 

Hello folks, thanks a lo for all these answer, I was far from the computer these days. Actually I don't really understand the questio about the "latching", it seems to me be explained in specs as they said it is "1NC SPST ( a single normally closed (NC) contact and is a single pole single throw (SPST) type. This means that the contact is closed when the push button is not pressed and opens when the push button is pressed.)
Also it seems to me that the push will stop the circuit and to start it again you need to turn the switch to go bavk to normal position. Don't you think? Here is the link : https://www.amazon.fr/Taiss-Verroui...-1-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&psc=1

 

There are usually just two methods for E-Stop circuits, one is the N/C , Momentary stop button, in this case, a N.O contact on the controlled E-stop relay is wired across the N.O. Start P.B. in order to retain the relay, when the E-stop is pushed, the contact opens, and the relay is no longer retained.
The other is the Push-on-Latch N.C. P.B. when pushed, this keeps the circuit open until the P.B. is released and unlatched to the ready state again.

 

E stops are typically ‘maintained’, cutting power to the circuit. If you don’t want resumption when closing the circuit, add a start/stop latch circuit. Currents that exceed the switch rating require a slave relay, or breaker trip unit.

 

As shown in fig2 page 6 of the Schneider circuit post #8.
This uses the momentary stop P.B. method.

 

yes, ok I will check this. Thank's a lot Max and Getdeviceinfo
