content: Search for "latching push button" probably with the remark "PCB mount" "right angle" ...Here is an example:push button switchyou would need to figure out the mode of operation however. It can be SPDT, DPDT, DPST... My guess would be SPDT ON-ON or DPDT ON-ON. Are there any manufacturer markings? Do you have a schematic?Regards,Frederik

content: Hello guys!Thanks for your help.I found that it says "ITT" on it. That is the only markings. However, that manufacturer doesnt seem so easy to find here.. So a equivalent would be great.

content: If it only were that simple. that dont narrow it down much, since they probably make more than just one switch.These are very close (i think) they are however latching, mine is non-latching.http://www.ebay.com/itm/10pcs-ITT-C-K-PHA2UEE-SWITCH-DPDT-PUSH-BUTTON-latching-RA-PCB-SP70300-0202-11F1-/121118476209?epid=1931526773&hash=item1c333947b1:g:4zIAAOxyHE5RpfQH

content: You need to figure out the switching action, then you can do the measurements on the pins to see what pitch you need. Afterwards Mouser, Digikey, RS Components, TME etc. will hook you up with various makes of switches that can quite easily be selected via your design requirements (type of switch, number of contacts, pitch of contacts, rated switching current,...)We can hardly do the guessing for you. Hell we do not even know what device this sits in (PSU is a little generic), apart from the fact that this might switch 10A as well as 0.01A. Without more information: No can do.

content: I might have found a replacement.C&K switch PHB2U0A1A seem to be a match.. also SN for angle..So PHB2U0ASN1A it is still in manufacture, however very hard to get hold of it seems.
