Custom Fire Button

[Vapors Tongue]

ok im well away building my own box , now i have bought i fire button to wire on to the pcb , i know which is positive and negative on the board but the fire button just has 2 pins with some tiny writing on the back and i cant make out what it says even using a magnifying glass but it does not look like positive or negative  or symbols that would look like a minus or plus , does it matter which pin is the positive or negative on the fire button ?

Doesn't matter when the fire button only has 2 pins.

could i use this to run a battery analyzers when i do a battery profile or does it have to be a coil ?

 

its an inline voltmeter

No..... that only measures voltage and gives a readout....

ok i thought it might no be right , just thought its firing and just doing the same job a coil would do but i had my doubts - thanks again
