foot switch for inspection development

[chris_kargotis1]

Anyone know where I can get a pressure foot switch for inspection

development?

They should be available in any good hardware store.

The ones that I got for my Zone VI timer are made by Treadlite. Cat.

No. T-51-S, Linemaster Switch Corp, Woodstock Conn. I also have one

that has no name on it but it looks exactly like the others. It was

designed for running a piece of equipment such as a band saw, I use

it to turn on my light box. You may find them with a "funky" plug to

fit a particular piece of equipment; that is easily dispatched with a

side cutter. As Michael said a well stocked hardware store is your

best bet.

Maybe I'm missing something here but I'll take a chance and maybe

just reveal my ignorance. While foot switches of various sorts are

readily available, if you're going to develop by inspection it isn't

enough just to find a foot switch, you also have to find a safelight

into with which the foot switch can be plugged. Since safelights

generally aren't meant to be operated by foot switches (I don't

think), that seemed to be an impossible task when I was looking a

year or so ago. Am I missing something here - is there some way to

just take any old foot switch and make it work with any old safelight?

FWIW,

I have my safelight plugged into one of the old Time-O-Lite

enlarger/safelight timers which has a 4 pin flat bladed port for a

foot switch. I think the type of connector used to be called a

Wollensak after the many a.v. devices that company made that used

that type of connection. But that could be wrong.

In the U.S. if you look around - old photo stores, garage sales, the

classifieds in the local paper, etc. you may find what you need. But

in The United Kingdom, I can't say what avenue to approach. You

could try B&H though - I'm not connected with them in anyway, but a

short search of their website produced the following options:

Now that I re-read this, I see that all Chris needs is a way to

interupt the circuit between the bulb and the outlet - a simple

spring loaded switch that can be operated with the foot can be

contrived via a trip to a hardware store, as Michael suggests, or a

Radio Shack, I should think.

Thankyou for your reply Sean and Michael. The thing is it's

difficult to find anything that's any good in the UK these's

days the place is falling apart.

I made a very inexpensive foot switch for my Gralab 451 with a

doorbell switch and a headphone cord. I mounted the doorbell switch

on a wood 1x4 about 8 inches long. I can rest my foot on the board

and hit the switch with the ball of my foot. The Gralab uses a TTL

input for the foot switch. DO NOT try running 120 VAC through this

type of a switch. If you must run 120 VAC through a floor switch

either by the industrual grade floor switch or make an enclosure to

house a microswitch. The risk of water getting onto the floor switch

running 120 VAC concerns me.
