searching a key switch...

Post by dacflyer » Thu Aug 14, 2008 5:24 pm

i am looking for a key switch simmelar to the one in this link

http://web2.automationdirect.com/adc/Sh ... GCX1470-22


but i need one that is NON-MAINTAINED ( springs back to center )
the switch above can be maintained from any position
i am looking for a key switch that is momentary from any position.
and neutral in center position.
i have looked in many other places, and cannot seem to find what i need.
anyone have an idea ? i'd like it to fit in a 20MM hole if possible,

Omron Part Number: A22K-3AC-11

That will give you a 22mm three position (Momentary-OFF-Momentary) key switch. Each MOMENTARY (spring return to center) offers one NO and one NC set of contacts.

The data PDF may be found here:

Scroll down to the A22K series. The cost is about $30 from Allied Electronics:

I am sure Newark and a host of others carry it.

cool, thanks for the info, i think this may be what i need...but i think i need the Omron Part Number: A22K-3AC-20
because this gives me both N.O. contacts, so when i click right or left only that switch closes..

thanks again..

Yeah, if you want NO then the -20 would be what you want. Hope that works out for you.

Good deal. Switches like that have the operator and the blocks so just a matter of the block. Hope it does what you want to do.

it should i am wanting to use it for a dumbwaiter project, have a control at the top and bottom of the lift. i am using relay to relay logic also.
so that once a up control is activated from one end, a down command is locked out, and vice versa...
