A traction switch is a switch that is operated by a chain or rope. An electric traction switch is connected to a typical switch of a tractor to be transported and the next tractor to be stopped. The most frequent use of a traction switch is to act on an electric ceiling lamp.

With an automatic switch, the power supply of the houses is switched automatically during a failure, which eliminates the need for manual switching. But with a manual switch, the owner must turn a switch to transform the power from the commercial network to the generator.

An interlock generator kit (or simply interlock kit) is a device designed to allow the safe supply of a house by a portable generator during a power outage. It is a cheaper alternative for the purchase and installation of a dedicated transfer switch.

The Interlock kit allows the safe disconnection of the power panel and the switch to the generator powered by a new switch. The Interlock kit allows only one of these power systems to work simultaneously, which prevents the two sources from connecting to each other.

The Interlock Kit allows you to disconnect the power supply panel safely and switch to the generator powered by a new switch. The Interlock Kit allows you to operate only one of these power systems simultaneously, which prevents the two sources from being connected together.
