Solenoid Switch Question

Is it ok to use a solenoid switch rated for continuous duty in a starter circuit (i.e. it will only see intermittent use)?

Regards,

Regards,
can't see why not,apart from current drain when on.

why not just use a battery switch?,pretty fool proof as well

Re: Solenoid switch question

Yes...

Your continuous duty rating is to ensure that the solenoid can handle the heat generated from continuous excitation... As long as the contact lifespan is rated high enough... Most assuredly for a starting circuit... 100k X max?

5 starts a day x 365 days x 10 yrs = 18.25k? Double the contact amp rating, and you for sure will avoid problems...

Re: Solenoid switch question

If the current rating is as high as what you need there is no problem. The difference between continuous rating and intermittent is the coil that pulls the solenoid in. Usually more expensive for continuous.

Regards,
The answer to your question is "Yes". If there is anything more that you didn't post, the answer might not be that simple.

Re: Solenoid switch question

Thanks. I figured it was ok but thought I'd seek some expert (re)assurance.
