Peterbilt Switchmate Series Gen 3

One bump of a paw and the window’s down. GEN 3 is the strongest SwitchMate we’ve built for the Peterbilt 579 — a hinged lid held shut by hidden magnets. Flip it open, flip it shut.

• Magnetic lid — concealed magnets keep the lid closed until you flip it open; one-handed access to window and lock switches
• Stops accidental window roll-downs and keeps your cab locked when you step away — your dog can’t unlock the truck while it’s running.
• Driver side, passenger side, or both — covers the left and right door switch modules
• Built heavier — 25% thicker lid, reinforced hinges, about 20% more material than GEN 2
• Slip-fit — no drilling, no permanent mods, comes off clean
• Carbon-fiber reinforced PETG — won’t warp or melt in a summer cab
• Made in the USA — designed by a working truck driver
• Lifetime warranty when you buy direct from SwitchMate
• Crete Carrier approved — fleet tested, not garage tested
