Contact Switch Gizmo

[thepennyarcade]

Hi All
I have seen this tube affair on my Mills Cross Diamond and on my Jennings Prospector.
When you look at the wires they seem to complete the switch circuit when the contacts are not touching.
But in reality the circuit is not closed until the contact point close.
Anybody know what this is and how it works?
Thanks
John

HI

That looks like a 10 watt resistor. Is there a number on the other side that states the value of the resistor?

Is that assembly located up by the top of the payout fingers, above the spring on the 20 pay finger?
Is this slot set up for casino play, bell and light, Etc?
Just curious!
My guess is a drop down resister to have maximum voltage to the bell, which would take more current and lower voltage to candle!
