Yamaha service manual shorthand

Duffalora · Jul 14, 2014

A quick question about Yamaha service manual notations. In the electrical parts list, if "2-2" is written after a push button switch, does this mean the switch is DPDT? Thanks.

Service manual is for a Yamaha RX-530. The power on-off switch has failed completely. It was working fine a couple of days ago but now it won't latch, nor can it be pushed in far enough to turn the receiver on if manually held in the "on" position. It's an Alps, and the dimensions match a standard Alps DPDT switch (Alps SPUN191400). It is SW501 in the manual and has 2-2 in the description (see below) so was wondering if this meant DPDT.
