engine idea when put into gear

[metal matt]

I'm looking for a bit of info from anyone with an MX5 build. When I put my car into gear the revs go up from normal ideal. I've done some reading and looking on the MX5 forums and they all point to the clutch switch. I currently don't have one but My question is what have you guys done about yours, fitted the switch or bypassed it.
