Anyone out there who’s more of a DIYer looking for special needs solutions may consider purchasing one of these Ultimate Switches from Enabling Devices. For ~$60 it might look like a cheap buy next to some of their other devices like this ~$250 Little Tikes toy.

Ultimate Switch

Inside the Ultimate Switch is nothing more than an Omron single pole single throw momentary switch.

Digikey previously sold the same switch for $30 at one-off-quantities, you can likely get it cheaper from a supply house or from Omron directly in their industrial automation limit switches category.
