My Olympus OM30 won't shut off when the switch is in the "OFF" position?

[howdoesonecla]

I recently replaced the switch on my Olympus OM30 which allows the user to switch through different camera modes such asbulb, manual, auto and battery check. Before i swapped the switch the camera was stuck in the auto position even when switched to any of the other modes like bulb etc. After swapping the switch the camera wont shut off at all and the light meter still operates even in the OFF and B (bulb) position which ends up draining the batteries so every time i want to put my camera down i have to take one of the batteries out. Is there any way I could fix this?
