These are three-position selector switches with maintained action. This product is one of the shortest illuminated 22.5 mm switches on the market. The depth behind the panel is 48 mm (1.88"). By default, each SW21 switch comes with two NO blocks.

It allows you to keep either one of the two channels closed and one open, or keep both channels open.

Postion explanation (2 NO Blocks):
Selector Position 1: Keep Channel 1 closed and Channel 2 open.
Selector Position 2 (Center Position): Keep both channels open.

See the BK-SW15 of additional switch blocks. Whether the block is a NO or a NC block is printed on the side of its block. This can also be identified by looking at the bottom of the block. A green round dot indicates a NO block; a red round dot indicates a NC block.
