Footswitches

Footswitches for MetroLux

Both MetroLux (early) and MetroLux II can accommodate a footswitch or two.  MetroLux early had one footswitch socket in which to plug a footswitch.  When used, the footswitch had the option of operating either the START or FOCUS buttons.  Usually it was the FOCUS button, as the selection was made at the factory.

The MetroLux II has two footswitch sockets, one for each function : EXPOSE and FOCUS.

Original footswitches were a product of Linemaster.  Here's a picture of the three I have.



One is a T-51-PS and the other is a T-91-TS.  The one on the right is different and I've had to adapt it, so don't buy that one unless you want to change the connector.  These switches are usually available on eBay.  I'm sure there are others that would work fine, but I don't know what they are.

Here's the connector you want.



It's called a 1/4" phone connector, mono.

OR, you can make your own footswitch if you're handy with such things.  You'll need the phono jack, wire (lamp cord is fine), a switch (single pole, momentary, normal open), and some kind of mechanism to hold the switch under your foot.  The voltage present is very low, only 5V.  There is very little current flowing with switch closed.

I assume no liability.  To the best of my knowledge, what I've posted here is true.  This posting is offered as guidance only.  If you are not sure, then DON'T DO IT.
