Frans,
only that we speak the same language:
an ON/OFF/ON is a 3 position switch
an ON/OFF/(ON) is a 3 position switch, where 1 position is springloaded, that means the switch is going back to OFF when you release your hand
an (ON)/OFF/(ON) is a 3 position switch, where 2 positions are springloaded and going automatically back to OFF when you release the switch.
For the buttons in our case we are using 2 position buttons. OFF/ON when the button has to positions.
OFF/(ON) when we have a typical button with a spring.
I don´t know if this is easy to understand?
FDS delievered 2 types of buttons. The OFF/(ON) type and some OFF/ON where I don´t know to use them.
Can you answer this?
Regards
Ralf
