I hadn't seen these before. Thanks for posting.
Bizarre Amazon pricing:
amazon.com, shipping to Canada: $19.95 US + $9.67 US = $29.62 US = $40.36 CDN
amazon.ca, CDN$:
green switch: $31.11 + $5.64 = $37.75
red switch: $54.06 + $5.54 = $59.60
any color you want, incl. connecting cable: $90.36 + $5.54 = $95.90
Cable must be oxygen-free copper
