A museum display of two types of electro mechanical switches I used to repair. Bit weird when you see your job in a museum but thats progress. The top part of the switch is the relay control. Each relay operated a set of contacts (the bits with the silver front and a letter stencilled on). The contacts will provide a path for a circuit to perform certain function's including controlling the electro mechanical device on the bottom half.
The bottom half is operated by two large electro mechanical magnets with associated gear, they step the mechanism up then make the wipers (the contacts) sweep across the bank to the desired outlet. There could be many hundreds of these in one room clattering away and maintenance intensive. I can still smell them and hear them and you knew when a motor or magnet had burnt out and in all the cacophony of noise in a telephone exchange, you could hear one out of hundred misstep.

When you go to a museum and see the kit you used to repair on display. And muscle memory kicks in on how to remove and actions to test and repair. Still have the tools as well.
