Review on INTELLITEC 0100055000 Battery Disconnect Relay by Cardell Haynes

The advantage of a latching or monostable solenoid is that it draws ZERO current in either state. When your car is on, there is no 0.2A DC current like a regular magnet. The relay itself is basically the same as any starter solenoid with a locking mechanism on the bottom so you don't have to worry about high current draw including the car's starter. (Unless it's a diesel) I've made a simplified diagram for those who want to hook it up to their car. The toggle switch is double pole, offset from center, instant action. Designation (on) off (on) when searching for a switch. You do NOT need a switch without a spring! Switch wiring can be very small, even telephone wire, as the magnet requires very little power to operate. The Bosch relay circuit is an option that prevents accidental disconnection of the battery while driving. As long as the key is on or the Bosch relay is activated by the timer (cigarette lighter, light, etc.), the battery cannot be disconnected. (Bad idea when the generator is producing electricity). After the vehicle is shut down, the solenoid can be switched to the off mode, resulting in a "dead" vehicle. Ideal for theft prevention. When the solenoid is off, it's totally dead even if someone has the car keys. Hide the switch in a hard-to-reach place. If your vehicle is rarely used, the battery is isolated and parasitic current drains cannot harm it.
