Throttle Switch

I don't know about the BN1 throttle switch whether it is same or different from later switches, but the standard method is to loosen the nut on the clamp where throttle rod attaches and turn screw slot so it is vertical when the throttle is closed. The screw slot is parallel to cam face. When operating correctly, the throttle will have to open about 25-30% to trip the switch and cut power to the OD. You can use a test light attached to the connections to verify this.
 
Bruce, I wrote this some time ago when talking about adjusting the switch.
"I know I'm going to sound simplistic, but maybe this answer would work for you. the previous owner of my car eliminated the throttle switch. The switch is still there but the wires are just spliced thru solid to eliminate the action of the switch but make the firewall etc look original. With this arrangement you only need ensure that you have some accelleration on (even a wee bit) when you flip the dash toggle switch. It works beautifully, does great downshifts coming off the freeway and eliminates one possible hassle with the circuit. I drove mine that way for (7) summers with no trouble. "

I bypassed my the same way years ago. No problems. I just depress the clutch then switch out of OD, just like downshifting the transmission. Switching up into OD is simply by flipping the switch, no clutch required. Works well for me.
