The switch you're referring to only turns the meter movement on and off.
The "main" switch is the switch that closes when the mirror starts to go up.
You can't safely get to it from the outside of the camera. Older OM-2s have
a flat reed type switch that can chatter while it's closing. This
chattering alone can cause lockup. All 2Ns and maybe some 2s have gold
plated wire main switch that's more reliable and needs far less cleaning.
