OT: Light duty dual pushbutton pendant

kolyur · Oct 24, 2014

I've been Googling this for an hour and haven't come up with anything. I need a small handheld pendant for jogging a machine. It needs to have two buttons (24vdc low current and they could share a common). Something like in the picture but with an extra button.

So far everything I've found with 2+ buttons are large, heavy duty units meant for a crane or hoist. This is a very small piece of equipment and one of those bulky pendants is overkill and would look silly.

The icing on the cake would be something readily available from a reputable supplier... any suggestions?

You need one of those remote gate/garage door openers I'd start looking there.

Sounds like something you could make easily with a small enclosure and some switches.

I've used these guys before for a lot of smaller enclosures:

I'd personally also add an M12 receptacle for changing the cable out if it gets damaged.

Yeah that will probably be my Plan B if I can't find anything pre-assembled.

We use a "jog pendant" made by A/B which is really nice, probably overkill and expensive, but the really nice part might get ya. It is easy to use in my opinion, and our operators like them. It is bulky enough you will need a nice bracket to hang it on when not in use, but the grip makes it easy to handle.

Here's the line (we use the one with the mini e-stop on it).

I haven't used these models, but the rest of their line is solid.

Search for a Banner jog pendant.
Dead man switch and all and not bulky nor expensive.
I don't have any documents with me so a search may work for you.

Opss easy enough with goole, here you go:

The switches inside a mouse are good enough for this.

McMaster Carr has a surprisingly nice pendant selection.

We have used 7987K28 and it's not that large a clunky

You could also go wireless, using a small handheld transmitter. We use the ones from this company :

These are designed for crane controls, but can be adapted to many other uses and allows the operator freedom of movement.

Thanks for all the suggestions. I found some small crane pendants in our stockroom so I think I'll just use one of those... nothing beats free.

I like the look of some of those enabling switches like the Banner unit but they're all big $$$ due to the safety rating.
