Push Button: Normally Open Momentary Switch with a Cushioned Contact (De Reamer, GE 1939)
A panel push button that closes a circuit only while you press it. A spring holds the button out, and a metal rim on the end of its rod sits clear of two contacts. Press it and the rim bridges both contacts. A second spring inside the button lets the rod give, so the contacts never take more than that spring's force.
Source: Frank C. De Reamer, US 2,166,803 (General Electric, 1939), Fig. 5. Unknown: the insulating material, the metals and every size. De Reamer gives none of them, so they are linked to unknown heads. The tools are ours. Picture: the patent's Fig. 5.

Make a drawn metal tube closed at the top, and a rod with a head. Put a small coil spring in the top of the tube, then the rod's head. Wedge a washer into the tube under the head. Leave clearance so the rod can swivel a little. Turn the rod's lower end down to a smaller diameter. Unknown: the metal.

Assemble
Assemble
Set the terminals in their recesses and the contacts in their grooves. Slide the button into the sleeve, with a coil spring round the rod between the cover and the wedged washer. Pass the rod's end through the cover's hole. Put on it a loose insulating washer with a metal rim round its edge. Hammer the rod's end over into a flange. Lay the cover on the housing, so its ears clamp the terminals, and bend the plate's tangs over the bead.

Check it
At rest, the rim sits against the underside of the cover and the circuit is open. Pressed, the rim meets the stepped ends of both contacts and closes it. The checking is ours: the meter reads open, then closed while pressed.
