Is there an either/or switch

NickMoore1968 · May 3, 2020

I need a switch with two live outputs whereby I can switch between L1 and L2 but not permit L! and L2 to be active at the same time. What would you call this type of switch?

A simple two way switch with no off position. 240v small load. I need a wireless version of this switch to turn my hot water on and off.

SPDT or single pole double throw would be the normal way of describing this.

Just look for a wireless switch which has SPDT contacts, or possibly described as changeover, NO/NC contacts.

What sort of water heater is it?

The controller is a Tiara 425. Already replaced room stat with a wireless one - works lovely. So now want to leave controller on 24hr hot water and wire in a wireless switch.

That doesn't answer the question, but I'm going to guess that you mean that this is to control the hot water zone of a heating system with a gas or oil boiler and not an electrically heated hot water system of any kind?

Correct - the hot water is heated by gas. The controller/switch is of course electrically operated but very basic and clumsy. I intend to leave the hot water circuit on 24 hours and wire my wireless switch into this.
