Wireless Switches: Do SPDT and SPST wireless switches exist?

rimcanyon · Apr 1, 2020

Note, the title is wrong but I can't edit it. Should be do SPDT and DPDT wireless switches exist?

I have a control issue I need some help with. I want to replace an existing 110V 15A DPDT switch with a wireless switch so that I have remote control. Can't find anything. Is my only option to use a wireless SPST switch to trigger a relay that is wired so as to simulate the DPDT switch? Wireless SPST switches are readily available.

Thinking out loud, could you use two Wemo switches combined with the IFTTT app (if this then that) to make one the master and the other the slave and tell IFTTT to switch the slave to whatever is the opposite of the master.

Would help to know more about the application, or what you are trying to do. There are wireless DPDT using dual relays, example below states it can operate 30A.KT-G3-A USA 4G GSM AUTO Relay Switch 12V Solenoid Remote Control Box Wireless Gate Opener 2CH Output HOG Trap System 30A Relay Contact, you can get a WiFi chip. Probably other variants, including hand remotes.

I am not aware of any wemo switches that are spdt... You are right that a pair of spst switches plus IFTTT could emulate a spdt switch, but then it would take four spst switches to emulate a dpdt switch, and you would have to solve some initialization problems and timing problems. OTOH, a single WEMO switch along with a Deltrol 8030 DPDT relay gets me the behavior I want. I was just hoping to find a solution in a single package.

Mksj, interesting devices you linked. The first one might do it, but it requires a SIMM card and communicates over 4G. Thanks.

There are also numerous relay version listed on eBay that are WiFi, Alexa, smart home, etc. Do a search "Relay Wireless wifi" or use whatever wireless connection you are looking for. There are also a lot less expensive GSM models.

Well, I should give some more info. about the application. The DPDT switch needs to handle 15A. I really don't need any additional functionality, just a simple DPDT wireless switch or relay.

Google "dust collector wireless switch" and you will find various products for 120VAC which will probably be SPDT and for 240VAC which will be DPDT
