Many motorists in a hurry to install in your car the so-called device to turn off the “masses” with which, without removing the terminals, the battery easily detaches from the electrical outlet. Nothing difficult here — just need to buy at the store is one of the commercially available mechanical switches and secure it in a suitable place under the hood. Is and switch the RAD-1 remote control, which will save you from having to open the hood. It is true that the control device remains under tension, and to disable the “masses” directly from salon of the car there lay a long negative cable and drill the hole in the cowl panel.
We offer our readers a diagram of the electronic switch the “masses” that do not have mechanical contacts and are therefore more reliable and durable. In addition, this device can be used as a theft deterrent.
E-switch the “masses” consists of only two semiconductor devices: SCR V2 (see wiring diagram) and semiconductor diode V1. The first serves as a solenoid, triggered by the presence of even a short-pulse ka control electrode. Such a signal can be obtained, closing the microswitch S1 mounted in the cabin. Then, the SCR V2 will open, the resistance will be small, and through the device may leak significant current. However, the SCR passes current only in one direction — from the battery to the on-Board network. And that battery could be recharged from the alternator in parallel with the SCR, but in the reverse polarity it included a diode V1.
