Push to close buttons.

[pete10uk]

Hi All

 

I'm looking for a supply of pre made push to close button units with 9 or so buttons.

 

I have a number of audio players with a trigger connector where I want to give the client a push button to trigger, I need 60 units so would prefer not to make them. Something like a number keypad would be ideal but all I can find is a matrix style resistance connector but I need simple push to close.

 

Any ideas on a good place to start?

 

Thanks

Do you need fully isolated buttons or could they have a common ground for example? A quantity of 60 makes it worth creating a PCB with a PIC or a small AVR on it to scan, decode and provide 9 or so individual outputs. What's the input look like? 3.3/5/12volt? You then have a vast choice of telephone style keypads. Edited March 8, 2021 by DrV

Sorry, common ground is fine. I need it to be power free as I don't have any easy power available.

 

I don't know what power is in the circuit but it will be as low as it goes. The player is a brightsign HD unit.

 

Thanks

Is this style of button bank any use? Seems to come in various configurations and button types:

 

Grayhill keypads

 

Edit: there were other replies as I replied, so I don't know if my response is appropriate now...

I'm not sure these are the right look for this project.

 

Was hoping to find a site which might have a number of styles.

 

Thanks for the response.

Grid switch electrical faceplates would do, but would be a bit chunky - although Clipsal Australia do some high-density gridswitches with a lot of switches in a small box and Contactum have 8 in a UK double box.

 

If you don't want to make them, plenty of fabricators could

Seems pricey though

Good idea, yes is pricy but the model of player we are using is without the usb interface, if it did have usb a simple number keypad wold be ideal.

 

Looking at it I think making something is going to be the end result, I was hoping for a pre made unit I could just stick a Phoenix connector on and off we go.

Would a custom made membrane switch like these do? (Disclosure - I did some work for this firm.)
