I am building a floor lamp made of vintage elevator directional lenses removed from an old hospital. The lenses are from the 50's. I want to simulate an elevator theme for this project.
I have all that I need to illuminate these lamps. I used a 12V transformer to allow the use of low current 12V LEDs. I am using two 30mm power buttons to power these lamps on and off. A red LED indicates down, which powers the bottom lights. I am using a green LED button to power the UP button. A really cool looking option.
Now, to my real question. I have an old 12 V door bell that I want to use to simulate an elevator door ding. In other words, if you push the up / down LED button to turn on the lamps I thought it would be cool to hear the "ding" noise.
I have room inside my control panel to mount the door bell. I can use the power for the lamps to make the door bell ring once. The only issue is, the solenoid stays out and makes the coil hot.
I was wondering if someone knows what simple device I can use to drop power to the doorbell and keep the lights burning and only power up the 12V doorbell for only a fraction of a second and then release the power to allow the solenoid to disengage. I would like to do this for both up / down power buttons.
I tried / tested a relay that I thought would work but is not for a latching switch, only a momentary. The doorbell is also from the hospital. I believe I can add a third push button the the panel to allow a push the ding using a momentary switch but thought a push of the power button and the sound of the ding would be better.
