Question Solid state relay with NO and NC available ?

Does anyone know if there is an Solid State Relay with NO (normally open) and NC (normally closed) available ?

I have search in books and on the internet but found only solid state with NO or NC contact, but for savety issues I need both of them.

If someone know a type and/or a manufacture it will be very helpfully.

Thanks anyway,
Arjan Jaspers

Solid-state relays don't have "contacts"

You could buy one of each (NC and NO) and connect so that you created
a SPDT contact.

Hi !

Solid state C/NO/NC switches exist for low energy and low voltage leves. Try MAXIM - they have many.

If you want to switch higher voltages or isolated power then there is not much choice that building your application using two C/NO switches and arranging the controls so that you do not get overlap.
