The communications switch or "Cobra Head" was a hand switch used extensively throughout the Apollo program and figures in a number of iconic in-flight Apollo photographs. This particular switch dates to the late Apollo/Skylab era but I have not been able to ascertain whether it was flown in space.
Identical equipment can be seen in this photograph of Apollo 17 Commander Gene Cernan and Command Module Pilot Ron Evans, taken while on their return from the moon in December 1972.
Further acquisitions included an A7L IVA glove, minus it's thermal micrometeroid layer.
An identical glove undergoes quality control inspection at the ILC Dover facility in Delaware.
An A6L wrist disconnect in to which the Apollo pressure suit glove would be secured. It's a beautiful example of the precision engineering that typified the Apollo program.
Apollo space suit oxygen connector and diverter valve. This connector predates the Apollo 1 fire of January 1967. Following the fire, the white nylon release lugs were changed to brass.
This Thermal Micro-meteoroid Garment (TMG) layer of the shuttle Extravehicular Mobility Unit (EMU) glove dates 1980. With palms made from Kevlar and latex fingers tips developed for the Apollo moon suit it was designed with the maxim "stop a bullet but pick up a dime"... in mind.
The second glove is some 15 years later in design. Flexibility and touch has been improved by replacing the Kevlar with latex across the palm and fingers. The pull switch on the cuff operates heating elements in the fingers to combat severe cold experienced by astronauts when in shadow for prolonged periods.
