Press to activate the horn control and release to return it to OFF. The CH4X4 Toyota momentary horn switch pairs that push-and-release action with a laser-etched trumpet-shaped horn icon, making its purpose recognizable on the dash. The matte black square face offers an OEM-style appearance for a compatible Toyota opening. Use it with a compatible 12V horn control circuit and the required fused relay.
Momentary operation
The switch stays active only while pressed and returns to OFF when released. It is a momentary SPST control, not a maintained ON/OFF switch. This listing is for the switch, not a complete horn system.
