12 volt vibration switch

12 volt vibration switch

12 volt vibration switch

(OP)
Anyone know of a 12 volt vibration switch capable of triggering relays?

RE: 12 volt vibration switch

Yes. Google 'vibration switch 12V" and undoubtedly you will find some. Yours is a very vague request, and so I can give no more than a very vague answer. More detailed requirements are necessary otherwise!

RE: 12 volt vibration switch

(OP)
I'm sorry I was so vague.  What I want to do is activate a relay only when the engine is running without tampering with the original wiring.  Air flow switches, anything really that would activate only when an engine is running!

RE: 12 volt vibration switch

Most folks use an oil pressure switch, like a HOBBS switch to generate an engine run signal.

RE: 12 volt vibration switch

You can use piezo electric effect based vibration sensors which is available in the market.

RE: 12 volt vibration switch

What catserveng said. Use oil pressure to prove engine running. Proven technology. Been used for generations.
