I actually have a bunch of #555 non-LED bulbs that I'd like to use first unless there would be a problem lighting all five bulbs with one or two power adapters. If 6.3V or equivalent LED bulbs are used, can I use a single power adapter?
The problem would be that the 4.5VDC
300mA power supply you described can't handle the current draw for more than one non-LED #555 bulb because they draw
250mA each.
Best case, if the coin door has two non-LED #555s and the three buttons have 12v LEDs, they're drawing about
518mA.
- (250mA * 2) + (6mA * 3) = 518mA
Worst case, if all five lamps are non-LED #555s, they're drawing about
1250mA and the buttons on the control panel are roasting your fingers.
- 250mA * 5 = 1250mA
LEDs are your friend.
Paradise Arcade Shop has
these LED #555 replacements for the coin door (won't fit in some pushbuttons) and
white or
red or
blue or
green LEDs for the pushbuttons.
- These LEDs will run on that 300mA power supply with no problem.
Another question if anyone could help...I'm having issues pulling out the bulbs in this illuminated pushbutton. It doesn't seem to rotate to release like other light buttons I have or pull straight out. Any ideas how to access the bulbs?
On most illuminated buttons, the body of the button has tabs that fit into slots on the bulb socket/switch holder.
1. Put the switch back in so the arms are less likely to flex/break.
2. Rock the socket/switch holder as you try to turn it.
The rock/turn trick should work for tab/slot buttons (round) or peg/slot buttons. (triangle)
If your socket is a snap-in like the rectangular one below, wiggle the socket in a conical motion whle pulling and gently twisting.
