Part number for those cheap 3x6mm 2-pin SMD tact switches

[HSPalm]

Hi,
On many products I buy I find the same type of SMD tactile switch. It looks like the "regular"one, only cut in half. But I can't find anything similar on Digikey or mouser.
On aliexpress and ebay they can be found as "3x6 smd switch", in different heights. Here's a couple examples:

http://www.aliexpress.com/item/1000pcs-lot-3-6-4-3MM-touch-switch-white-SMD-2-feet-micro-switch-limit-switch/32336213908.html

I want a switch I can have my chinese manufacturer source for cheap, and also an alternative at digikey/mouser when/if producing locally.
I am interesten in part numbers, datasheets and compatible parts.

Sorry guys, found lots of them. It was the dimensions that fooled me, they're actually 6x3.5mm
