DG/Vishay-switcher

I always wonder what switch does what, so here it is:

Vishay also have switches with the DG3xx prefix (and others)

8p:

DG417: SPST normally closed

DG418: SPST normally open

Dg419: SPDT 

16p:

DG401: 2 x SPST in DIL16

DG403: 2 x SPDT

Dg405: 2 x linked SPST

Dg408: 1:8 mux

DG409: 2 x Linked 1:4 mux

DG411: 4 switches, normally closed

DG412: 4 switches, normally open

DG413: 4 switches, 2 pos and 2 neg logic, May be used as SPDT/DPDT

NB: Max +/-8V men kan funke med single supply opp til 16v:

Dg4051: 1:8 mux

Dg4052: 2 x linked 1:4 mux

Dg4053: 3 x spdt 

28p wide

Dg406: 1:16 mux

Dg407: 2 x Linked 1:8 mux

Dg445 - quad spst - what’s The catch?

Per the 12th of April 2022 I have:

2 x DG403 (dual SPDT)

2 x DG408 (1:8)

1 x DG409 (2 x 1:4)

5 x DG412 (4 x SPST)

1 x DG418 (SPST normally open)

8 x DG419 (SPDT)

Update

I ordered 306 Harris DG413 from Digikey as they were the cheapest I could find (around NOK 8.5). I also ordered 45 DG408 from Farnell, not as cheap, and will order 100 Intersil DG412 from Rs components (around NOK 8.5 too).
