I have a broken contact type switch but don't know what it's called to replace it. A cam turns and contacts a copper strip that has two parallel strips that have wire connected to each and contact points at the end of each strip. When the cm hits it the contacts meet and complete the circuit
What is this component called? Thanks.

Your image looks to be a crude home brew type Micro-Switch. They come in a wide variety of levers and rollers for activation. Here is an example:



Most are available with Common, Normally Open and Normally Closed contacts. They also come in high current versions.

You choose for voltage and current you wish to handle.

What is the instrument and how old is it?
I cannot find a switch like that. Options I can offer is to replace the switch with a micro switch.

Edit: Ron beats me to it.

 

Hi Dip,
As a temporary fix you could reattach the broken lead to this point, Red Arrow.
Take care not to overheat the plastic moulding.

Instead of trying to solder a piece of wire on to the remaining strip, I would try twisting some stranded cable around it.
Or you can fabricate a clip that slides on to the metal.

 

so tab is broken and you need replacement. finding old atrocity like that will be challenging. reason they are not around any more is because they are not insulated. but once upon time they were common in pinballs, door bells etc.

since the tab to attach wire is missing, and connection is done by soldering, i would just solder wire on the other side, like this:
