The Cole Hersee SureStart low voltage disconnect switch (48513) automatically detects battery voltage and conserves starting power by disconnecting non-critical loads when necessary.

Ideal for utility and delivery vehicles as well as vehicles with ancillary onboard equipment (snowplows, hoists and pumps), the switch prolongs battery life by preventing damage due to excessive discharge. It has a rating of 100 amps at 12 volts or 24 volts DC. Service life is designed to exceed 1 million on/off cycles, according to the company.

The 4.5×4×4.27-in. compact switch does not require a separate solenoid.
