Inside an Otis elevator button
🕑 Added 2024-04-04 03:57:46 +0000 UTCA visually nice elevator button with red LED halo. It operates at 24V and has other applications. Clones can be found on AliExpress with the keyword in the description of the video. Note that with this button the switch contact is also referenced to +24V so logic level circuitry will need a suitable interface like a resistive divider.

Just reminded me of - Haggunenon Admiral ship/Disaster Area stunt ship It's the wild colour scheme that freaks me out,' said Zaphod, whose love affair with the ship had lasted almost three minutes into the flight. Every time you try and operate these weird black controls that are labelled in black on a black background, a little black light lights up in black to let you know you've done it.'

Fancy-schmancy. In my day, switches were two live wires that you'd connect with your hands. We didn't have these lights and contacts and fuses and all. If you weren't smoking when you broke contact, you weren't doing it right.
