If in the UK use RS components
 

I know this is an old thread but I sourced my switch from RS Components Ltd. I expect they would ship to the US.
SPDT-NO/NC Roller Lever Microswitch, 3 A @ 250 V ac

• RS Stock No. 472-8291
• Mfr. Part No. V4NSYRUL

They are £5.72 each

£6.86 with VAT for 1 to 49 units + free shipping in the UK
You still have to swap over the lever.
