Data East Diagnostic Switches

On my simpsons, the momentary switch is broken, and I'm looking to replace it. It's a dpdt switch, but only 2 wires are connected. My question is can I use a simple spst momentary switch in its place while i search out a replacement?

Thanks in advance

I tried it. It works fine. So if your in need of a new switch, grab a simple spst push button momentary.
