English to Japanese Tech/Engineering Electronics / Elect Eng

Context (copied and pasted from the source text. No, I don't know what that "a" is doing there either ;)): "The E-stop pushbuttons are a push-to-set, pull-to-reset, self-illuminating, and have two sets of force guided normally-open contacts."

This is the first time I see this term and I can't find it in any technical dictionary. Does anyone know how to translate this to Japanese? Google shows a very small number of hits for フォースガイド, but they all seem to be related (nomen omen) to relays. Can I just say フォースガイド接点(or even コンタクト), or is there a better term?

All help will be greatly appreciated, as always.
