New Zero Plus (Made by Otehall Switches, Ltd; England, UK; Now Owned by Arcolectric Holdings Plc.) Micro Switches, MicroSwitches, 15A 250V Normally Open Contacts, PYE, Part Number 373/25/10.  Each bid quantity is for a Lot of Five (5) Switches.  You may bid / buy any number of lots, up to the total quantity available above.
These were purchased at an industrial liquidation earlier this year, and they were brand new in bulk factory bags.  We repackaged them in heavy Ziplok bags for resale.  Otehall products are not commonly seen in the USA, but they made a lot of aircraft switches for the RAF on the other side of the pond.  The quality looks superb in every respect, and they have a somewhat heavier and more durable case than similar switches made by Honeywell, Omron, Cherry, Mulon, and others.  We couldn't find a datasheet for this part number (373/25/10), so Otehall's production was probably absorbed into Arcolectric's product line.
The switches in this listing have two terminals, and their operation is Normally Open (N/O).  That is to say, no current flows through the switch until the button is pushed.  They operate exactly opposite from the switches controlling the light in your refrigerator, or the dome light in your car.  The button has a positive click" upon actuation, and it takes about ten ounces to press according to our scales.  The pretravel and overtravel of the button is roughly 50/50, with the switch contacts tripping about midtravel.
