Brake pressure switch boot procedure

[krjt]

I have a master cyl. reservoir where the two brake pressure switch boot sitting on top of the MC reservoir tank were leaking when I pressure bled the brakes.

Is this a simple pull off and press new pieces in or do I need to do something to hold the switches inside the reservoir when removing the boot? My fear was for the switches inside simply floating around if I removed the boot without holding on somehow.
