Hi all. Has anyone seen / used a 'light' switch that is just momentary rather than latching like a normal switch ? I'm sure that somewhere in the dim distant past, I have seen something that looks exactly like a single gang flat-plate rocker light switch, but is actually spring loaded back to the 'off' position. Or am I just imagining this in a senior moment ? I've looked all through the Tool Station catalogue, but nothing springs out at me.
Help confirming that they exist, or pointers to one, anyone ??
I have lights that use a momentary switch in some labs at work,but the switch is connected to a controller that uses the momentary output to toggle the state of the light.Other inputs come from PIRs so the lights go out when the area is unoccupied.
So,yes this type of switch is certainly available.try the MK Grid range
On a similar subject, I'm looking for a single toggle switch with a neon indicator which comes on in the ON position. [Obviously, I'd have to supply it with a neutral as well as a live and switched live].
I want it for my holiday flat, where the bathroom light switch is wall-mounted *outside* the bathroom. The light is frequently left on, and a neon indicator would provide a reminder to turn it off. I know I can get fused spur switches with indicators, but I don't really want the fuse.
Why not simply put a neon across the switch. Okay it'd be on when the light was off and vice-versa, but that just helps you find the switch in the dark. For UK switches, you can get a clear "base" that sandwiches between the switch and it's back box, complete with two neons, for this very purpose.
I've got several of the 20A DP neon switches that other people have suggested in use for this sort of thing.
I also have some instances of the sort of light switch where the whole faceplate rocks back and forth (most of which I use as wall light-switches that can be operated with an elbow while carrying something). I do however use some elsewhere and for these in a couple of instances I wanted a neon indicator (or two - in one case where the switch isn't being used for a wall light, I wanted 2 neons; one illuminated when there is power to the switch but the switched item is off, the other comes on when the switched item has power).
In these cases the tilting switch is mounted on a shallow (eg 16mm) plastic back box. I drilled the edge of the back box and fitted one or two of Maplin's "miniature round panel neon" indicators - see:

use these you do need to be able to solder fairly fine wires to the connectors on the backs of the lamps. I normally put heat-shrink tubing over the connections as well, to insulate them, and one has to do that carefully if you still want to be able to thread the lamp & wires through the 7mm diameter hole in the edge of the mounting box and still be able to thread the fixing nut onto the lamp - it's fiddly...
outlet. I presume that means that there's a knockout in one edge for bringing a flex out parallel with the wall? But does it also mean that the outlet terminals are of the "wrap wire around a screw" type rather than the usual hole + grub screw? If so, are they ok for a solid conductor house-wiring outlet cable rather than a flex?
That's so for the MK (?) ones I've used in the past.
The ones I've seen have holes & grub screws, fine with T&E. The sort of instance you might see one using flex for the appliance is with an immersion heater.
