Questions about Purecrea Flush Mount Pushbutton IP67 Stainless Steel 16mm 2P

Purecrea's "16mm 2P Stainless Steel IP67 Flush Mount Pushbutton" can be used for a doorbell or to control a device that requires a simple pushbutton action. However, it works on the principle of a push button, which means you have to press once to activate and once to deactivate. For a doorbell, this might work if you need a simple signal to ring. For a device that requires on/off switching, this push-button will serve that purpose, but you'll need to press once to turn on and once to turn off, as you mentioned.
