I need a circuit diagram and parts list to install a 12v DC


Posted on Feb 5, 2014

A 12v DC electromagnetic lock with push to lock and push to unlock using my existing LED indicator/switch. The switch should indicate green when unlocked and red when locked. The LED indicator/switch is SD-7175SGEX1Q from It is momentary contact and is intended to be used as a `push and hold to exit` switch which interrupts the circuit while it is being pressed, but I would very much like to use it as

it is esthetically perfect for my application. It is 12v DC and has 3 pairs of pins: I also have a SR-1212-C2ALQ High Sensitivity Relay Module, also from and also 12v DC. It is 2 amp DPDT with trigger inputs. If additional relays are needed, I would prefer to use relays from Seco-Larm, since I have had good ordering experience with them, but am open to other sources. I would like to optionally include a mechanical switch to energize the circuit in locked position when the door is closed. Once closed, however, the LED indicator switch should still be able to unlock and lock. Is it at all possible to use 2 switches, one for lock and one for unlock if the wiring will not allow the use of one switch (unsure till a schematic is made) optionally include a mechanical switch to energize the circuit in locked position when the door is closed. Once closed, however, the LED indicator switch should still be able to unlock and lock. Sorry to take so long to reply (I also work for a living). This is for the restrooms in a high-end home. The doors are pocket doors with a soft close and soft open mechanism. The idea is that the doors are normally open. When someone goes into the restroom and slides the door shut, it closes slowly and a leaf or magnetic switch will cause a relay to energize the circuit to closed and turn the led red. When the person is ready to open the door, they push the button and it turns green and kills the power to...
