Your typical 2-speed pump will have 3 1/4" male spades.
1 is a common for line 1.
2 and 3 are for line 2, they are what make it a two speed.
One of them is low speed and the other high, your toggle is what directs the current through the switch to the chosen speeds spade.
Don' use the screws to attach your wiring, purchase female spades.
If you or your installer are unclear on the manner in which to wire the switch to the motor pay an electrician to do it on your behalf. All it should be is a service call, these fitting are dirt cheap and he'll be intimate with the job at hand.
He'll be done quicker than you can write the check for his services.
I'm really shocked that the pool company is unclear on the proper wiring of this.
See ya,
Kelly
