This CH4X4 push switch for Toyota seat heater installations provides a clearly labeled ON/OFF control for an added heated-seat circuit. The Seat Heater Symbol is laser etched into the matte black face, keeping the dashboard layout easy to read.
Seat Heater Symbol: matching your heated-seat controller
Use the Seat Heater Symbol to label a suitable relay-controlled circuit. Confirm the heater or controller’s input requirements before connecting it; this single ON/OFF control does not provide temperature adjustment or multiple heat settings.

Wiring and installation — fused relay required
A fused relay is required in ALL installations. Do not power the accessory directly through this 3A, 12V switch. Route accessory power through a suitably rated, fused relay circuit to avoid overloading the switch.
Use the supplied wiring diagram and confirm the accessory manufacturer’s control requirements. The included connector and wiring pigtail provide the switch-side connection; they are not a complete accessory wiring harness. A suitable CH4X4 marine-grade waterproof 12V 40A relay with 4-pin harness is available separately. Have a qualified installer check the wiring, fuse protection and relay selection if needed.
What is included
- 1 CH4X4 Large Push ON/OFF switch — Seat Heater Symbol.
- 1 connector with wiring pigtail.
- Wiring diagram.
The fused relay and the accessory being controlled are sold separately.
