Polyswitches

Home > Products > Self Assembly Components > Polyswitches
These Polyswitches (resettable fuses) are designed into battery packs so that in the event a short circuit occurs, the battery pack is protected and the cells themselves don’t short out, which would render the pack unusable.

We don’t encourage people to make battery packs themselves unless they are competent enough to do so (and certainly NEVER with lithium batteries), but if you need any advice with any of our Self Assembly Components get in touch and one of the friendly team will help.

If you need a quote for large quantities of Polyswitches, please find the product you wish to enquire about and use the “Request a Quote” link below its pricing.
