Actuator switch

Here's a relatively simple question to make you feel smart:

I'm planning on wiring a two wire actuator (where you have to reverse the polarity) to a momentary push button switch.  The plan is : push button to open, push same button to close.  Could you pls verify that the following set-up will do what I want :

1) wiring the relays in this fashion :

2) using the following push button switch, with the middle lead to ground and the other two to the alarm lock output (86) and alarm unlock output (85) leads of the relays above:

3) What size fuse should I use before the 12volts hits the relays (this set-up will be on a motorcycle)?

Thanks for your help

the12volt,

Is there a way to wire up the recommended latching relay circuit so that I'd have an LED comes on and stays on whle the actuator is pulled in, and goes off and stays off while the actuator is extended?

Thanks....this place is a great resource!
