Review on Efficient Emerson 120 105711 Power Solenoid 12V for Optimal Performance by Jacob Schmidt

Used as a switchable battery isolator. The simple installation of a 100 amp permanent magnet has many uses. If you need an electrical isolator for audio or radio amplification equipment, check out this solenoid. Not mentioned are the White Rodgers 120-105711 silver alloy contacts, which help prevent sparking on the contact surface and increase overall life. The previous installations in the motorhome from 6 years ago are still in use.
