Boltswitch company has been building a fusible bolted pressure type true safety switch since 1953.

These are Quick-make Quick-break switches which use Class J & L fuses and recommended for service entrance equipment.

The first switch to pass the 200,000 amp closing test and pass the required temperature tests with fuses in place.

We use our bolt pressure design in a true manual load break transfer switch.

We also manufacture a enclosed battery disconnect switch recommended for telecommunications applications.
