The Half SwitchMate guards the Peterbilt 579 window and lock switches — the ones that get bumped the most — and still gives you quick access while you drive.
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
Friction-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
Best for cats and lighter pets. Running a big dog? Step up to GEN 2 or GEN 3.
Fits: 2017–present Peterbilt 579 (same module as Kenworth T680 / W990). Match your switch module to the product photos before you order. Not sure? Send us clear photos of your switch module and we’ll confirm fit.
International orders (Canada): Import taxes, customs duties, and any sales tax are the customer's responsibility and are collected by the carrier or customs at delivery. SwitchMate USA does not collect these charges.
No double-sided tape, no drilling, no mods. Snaps over the factory switch module in about 30 seconds and comes off just as fast. Moving trucks? If the new one has the same style switch module, your covers go with you.
