3 position switch ; ON-OFF-ON

[Marcus John]

Hello
I'm after a switching solution to my shed exterior lighting.
The shed is located 20metres from my house and is currently switched locally by a standard weatherproof on/off switch.
I'd like to have remote switching to illuminate my path down to shed.
I've looked at PIR switching but the range seems to be limited to about 12 metres.
I've looked at wireless switching but that's very expensive.
I like the idea of photocell switching but i'd like the option of an override facility to manually switch on the light before twilight or after dusk or to switch the lights off completely i.e when i'm away from home.
I was thinking of a switch that can switch the line conductor ON-OFF-ON and to be weatherproof.
Cheers

@Markus, This entire thread makes no sense regarding your proposition for "ON OFF ON" switches (whatever they are).

You presumably have a supply cable with one line conductor, you can switch in one place only. (ie your shed, or if you chose to change where the switch is located, at the house).
You need another communication "channel" (ie a spare cable core, RF switch or PIR) to do both.
PIR will probably be disappointing, walking straight towards a beam from a long way won't work very well.

(You might ask your electrician if the underground cable is 3 core, and thus if it's possible to use the SWA as CPC, freeing up a core. - That possibility depends on several important design issues beyond the scope of this thread. Also, the work to organize that would in any case, soon become more costly than a cheap RF switch.)

Makes sense to me mate........it's just a single pole double throw switch but has a third function of being able to open both circuits. Line conductor to common. L1 to outside light / switch live. L2 to photocell switch supply then photcell switched live to L1 of SPDT switch. Switch will provide me lights on conventional way, lights on via photocell or lights off.

yes but having the third function of 'no throw'

It's not a third function, it's just center off.

Use a 2 gang 2way switch, switch A to act as a main switch feeding switch B common, one side of switch B feeds PIR, other side overrides PIR in parrallel and switches lights directly. You would be able to
1. Switch off everything and inhibit PIR from switching on in low light.
2. Switch on switch A and use switch B at any time to energise the outside lights even if the PIR fails
Could be a cheaper solution using simple components

Sorry man....I was led to believe a switch functions by turning a piece of equipment 'ON' and/or 'OFF'.

installed this ( yes it's from china) over 1 year ago. it's in a IP55 adaptable box, outside. works fine with 1 small glitch. every so often it sticks ( stops switching) and just needs power flicking off/on to reset. for the price, though, a good buy.
