Hello, welcome to the DigiKey TechForum,
The switch in the second picture looks something from the YB series from NKK switches, which we have options to chose from HERE.
I am unable to identify the switches in the first and third picture, are you able to provide any part markings along with the following information and we can try to find some options to consider.
We would need information such as switch function, panel cutout dimensions, measurements of QC leads, illumination color, actuator marking.
Based only on the photos it’s hard to tell much about the first and third switches.
The first one is a panel mount rocker switch rated for 100 to 125V.
It most likely:
- has a pilot lamp in the circular rocker handle
- is rated AC for US power
- is SPDT
One of these may work as a replacement, however it could also burst into flames since we do not know the exact electrical ratings of the switch. That said, here’s a search result link of the switches that may fit and work.

The third switch is marked NC (normally closed) 3A, 125V and it’s a panel mount push button switch.
These may work as replacements:

There is a very good chance that the original design of the circuit can use a much broader range of switches and still function normally. Often a huge range of switches will work (e.g. a 3A switch usually works where a 0.3A switch is required) and the design choice was just made based on price and availability on the day they ordered the parts.
