How to use a nc switch to activate a buzzer when pressed
i don't know if this is possible but, i want to be able to :
have a buzzer come on when a nc switch is pressed, for example, i have an emergency stop switch which is nc, so when pressed the circuit is broken,
i would like it so when i press the switch ( ie it breaks the contact ), it makes a buzzer sound and an led come on to notify that the emergency stop has been pressed,
i am using 8 core Ethernet cable to connect the emergency stop switches so if i have a circuit in every switch , i can do the same in every stop switch with the cable i am using,
i want a buzzer and an led in EVERY emergency stop switch, i will have 3 in total,
is it just the case of wiring the circuit in the one emergency stop and connecting the leds and buzzers from the others in Parallel at the other stop switches ?, or do they have to be wiring in series ?
i have got 6v and 12v buzzers and many value of resistors so the source voltage for powering them really wont be a problem,
the biggest problem is building the circuit, because atm it is a nc switch so if i connected an led and buzzer, it would be connected all the while, i need to somehow use the nc switch to break a circuit but also use it as a no switch for the buzzer circuit,
if this is possible please leave a comment and help if you can,
i have looked on google but cant really find anything,
hi also ad an addon to the question, the nc switch will be switching 230v, so the live cable will be cut and put accros the nc contacts, will this still work with iceng circuit or is that a big nono ?
