'automatic' shed light

[AndrewP]

Hi, I am setting up a layout for my 4 year old son and I'm wanting to have an engine shed light come on when he switches the points for the engine to 'go to bed' as he says. How do i do it? If i wire the lighting to the track it is variable voltage and will only glow once the loco is moving. If i wire it through a switch using the 16v transformer output then it can be switched on/off regardless of the points. I would like to wire it so that when he switches the point it will turn on the shed light and when he stitches the point back the shed light goes off. I am thinking of using LED's. Any idea's?

How are the points controlled?

 

A microswitch mechanically linked to the position of the points is one solution.

Hi Crosland, at the moment it is by hand but plans are for a point motor.

do you have ebay links for a microswitch?

thanks
