Description: Small in size and lightweight This remote switch remotely controls up to 2 electrical devices on the aircraft model through a switch channel on the remote control This device does not require calibration and can be accurately compatible with various brands of remote control equipment. Use receiver power supply, completely isolated from external power supply, external power supply, only for controlled equipment. 1 channel servo signal input, control 2 way electronic switches 220V maximum controlled voltage 2-way outputs Compatible with all brands of remote control devices without calibration Application range: Remote launch model rocket launch Remote control model Control of weapon system like real machine Headlight control of model aircraft Control of various remote switching systems Typical application: Connection: Plug the signal input cable into an idle receiver channel, which corresponds to a switch on the remote control. Connect the control switch and equipment Trigger: (Take the throttle channel as an example) Turn the throttle stick on the remote control to full throttle, and a relay is closed (that is, the wires at both ends are connected). Turn the throttle stick on the remote control to half-throttle. Both relays are not closed (both are not turned on). Turn the throttle stick on the remote control to the minimum throttle, and the other relay is closed (that is, the wires at both ends are connected). Package: 1x Electronic Switch Controller Note: Only one relay can be closed at a time The maximum current of each relay switch is 10A Only support 5V voltage receiver, otherwise the module may be damaged. If the receiver and servo use high voltage system, a step-down module should be added to the module.
