DC 12V 24V Single-channel Wireless Remote Control Switch for Car Access Control

This single-channel wireless remote control switch provides a convenient way to operate car access systems, gates, doors, and other 12V or 24V DC devices from a distance. It eliminates the need for hardwired control cables, simplifying installation and improving flexibility. With intelligent learning code pairing, you can quickly synchronise the controller with compatible transmitters without complex programming. The inching (momentary) operation mode sends a brief pulse each time the remote is pressed, ideal for triggering relays, latches, or momentary switches.

Features and Construction

The controller is built for reliable performance in vehicle and outdoor environments, with a robust relay output and a wide operating temperature range.

Material and Build

The switch controller uses a durable ABS plastic housing that protects internal electronics from dust and minor impacts. It is compact enough to fit behind panels or in small enclosures, with screw terminals for easy wiring. The unit is designed for low-power DC systems and operates efficiently without generating excessive heat.

Size and Practical Fit

The controller is small and lightweight, approximately 7cm x 5cm x 2cm, making it easy to mount in tight spaces such as vehicle dashboards, gate control boxes, or security panels. The wiring terminals accept standard stranded wire for straightforward connection to power and load devices.

Uses and Placement

This wireless switch is suited for a range of control applications where running cables is impractical or inconvenient. Its flexible voltage support (12V or 24V) and two frequency options add to its versatility.

Car Access Control

Ideal for operating electric door locks, boot releases, or garage door openers in vehicles with 12V electrical systems. The inching action works well with momentary relays used in central locking retrofit kits or remote-start devices.

Everyday Home and Commercial Use

Can be used for remote control of gates, barriers, alarms, or pumps in 24V systems. The 433MHz option helps avoid interference from other devices, and the learning code system allows pairing with multiple transmitters for shared access.

Benefits and Buying Value

This controller offers practical advantages in reliability, ease of setup, and flexibility, making it a cost-effective solution for remote switching needs.

Reuse and Low Maintenance

Once installed, the solid-state relay and passive receiver require no routine maintenance beyond occasional cleaning of contacts. The unit draws minimal power in standby, preserving battery life in 12V systems. If you move or replace equipment, the controller can be reprogrammed with new transmitters easily.

Why Choose This Product

Compared to hardwired switches, this wireless unit saves installation time and avoids drilling holes for cables. Its dual-voltage support and two frequency choices provide flexibility for different setups. The intelligent learning code pairing is straightforward even for DIY users, without needing specialised tools or software.
