Lee,

A search of completed items on ebay came up with 31 hits for
"Proximity Switch" and another 28 hits for "Proximity Sensor"
Of those 59 hits only about 15 - 20 were even bid on. Email
the seller, ask if they still have them, and offer what you will.
Many of them are sold in sets of 2 or more. You can probably
get them for $5.00 each
