Push button for AKSA

Felipe · « **on:** 5 Jan 2005, 05:20 pm »

hi,

I am looking for a vandal proof switch, completly flat, stainless steel type.
I saw a couple at rs components, but all seem to work with 24-48 Vdc. What i am looking for is a 240Vac to put in my 100w aksa. It will be placed between the mains and the transformers.

Does someone know a good supplier of these push buttons in Europe?
Thanks guys.

Felipe

I have bought a key lock, 240 volt on/off switch. I am going to install it in my GK-1 pre amp. Stops "the kids" using my hi fi as a party noise machine. I bought it at Dick Smiths (Australia Radio Shack).

RS do a 240V 5A anti vandal switch of the type you seek but I think you'll find that the amp really should have a switch rated to 10A unless you are using a relay to protect the switch. The switch will definitely work but it may not last all that long. Some owners are indeed using them for their amps so you are best of waiting for a response from them as to longevity.

I plan to use a switch like this one for my GK-1 which only needs a 2A switch so something like this should last forever.

Image of flush mount version is below and RS Australia stock no. is 841-609 and 841-615

Be warned though.......RS Australia wants a bit over AU$31 for this switch. And thats ridiculous.

Altronics has something very similar (www.altronics.com.au, Cat No. S0950) for AU$4.95 but again it's only rated to 5A

Felipe.
Ron R did a beautiful amp that used a couple of RS switches. I have used the same one and a relay (thanks for that, Ron)

The switch is ok to use with the relay which is a pulse type (I have 3 channels running off the one relay). The 2 together with postage cost me nearly AU$100.00

but the switch is a nice, tough unit that I think I'll use on all versions of the front face I will do over the years.

If you look on the RS site type these No's into a search and see how you go...

240-1231
244-0040

Thanks for all the answers guys!
The 240-1231 switch from rs looks like a good deal, and not very expensive.

About the coupling with the relay, what does it do exactly? It limits the inrush current when started?
Because i intend to use a dedicated circuit designed to do so - INRUSH CURRENT LIMITER FOR 240VAC from Experience Electronics. This keeps my power board from firing when i switch on the 2x 300VA toroids.
I assume this substitutes the relay in a more quality based solution.

The GK-1 doesnt need this i assume...

Very nice looking push button. However, it only take 50mA, 24V dc.
BTW, the 240-1231 don't look like it can fit over thick panel so check before you buy.

Have fun,
Sam

Turns out that RS can supply 10A 240V sub minature microswitches and they are just AU$5.50. Actuation pressure is just 250 grams all contacts are silver and they're rated to >10,000 operating cycles.

Could be a nice (and significantly cheaper) alternative if used with a SS actuator.
