Overview
The EDK-2319 is the door-panel switch a driver uses to aim powered exterior mirrors. It follows the layout most drivers already know: a four-way direction pad in the centre to tilt the selected mirror up, down, left and right; a pair of keys to choose which mirror — left or right — the pad is driving; and a separate mirror-heat key to clear condensation and frost off the glass. The switch reports those commands over the cab harness to the mirror actuators and the heating element; it does not carry the mirror motors itself.
Electrically it is specified as a durable cabin switch: a 24 V rating with an 18 – 32 V working window, a voltage drop held to ≤ 200 mV, and insulation that withstands a 550 V / 50 Hz impulse without breakdown. The 6 – 10 N key force gives the positive, deliberate press a driver expects from a mirror control, and every legend on the face carries a symbol marking to GB 4094-1999 so the function of each key reads at a glance.
Multi-key layout with mirror heat
The multi-key format is what separates the EDK-2319 from a compact rotary module. Because selection, four-way aim and mirror heating each get their own dedicated control, the driver can heat the glass or switch sides without hunting through a single knob's modes. That matters most on vehicles working in cold or wet climates, where a clear, quickly de-misted mirror is a direct safety item rather than a convenience. Programmes that would rather trade the extra keys for a smaller footprint can use the rotary TDK-2307 adjustment module instead; the two share the same 24 V electrical envelope so a platform can carry either without changing the mirror-actuator side.
Durability & environment
The 50,000-operation rating suits a control that is set at the start of a shift and adjusted only occasionally after that, while still holding its key feel and clean contact across years of service. The −40 to +85 °C working range covers vehicles that cold-soak overnight in winter depots as readily as those working through hot, humid summer duty. As a door-panel interior control the EDK-2319 is specified for the protected cabin environment rather than direct water exposure; confirm the panel cut-out, key legend set and connector orientation with us at quotation.
Compliance
Symbol markings follow GB 4094-1999 for driver controls. Programme-specific requirements — material declarations, customer standards and destination-market approvals — are confirmed on a project basis; a declaration of conformity is available on request as part of the PPAP package. Key legends and the backlight scheme are specified per programme.
Manufacturing & testing
Built under IATF 16949 with APQP project planning and a PPAP package available for OEM programmes. End-of-line testing covers contact make/break on each key and each direction-pad position, voltage-drop sampling against the ≤ 200 mV limit, operating-force sampling against the 6 – 10 N window, and connector retention. Endurance to the 50,000-operation window is verified on a sample basis in our in-house lab when a programme requires fresh validation.
How to ask
The EDK-2319 belongs to the Switches & Sensors family. For a compact rotary alternative that puts mirror select and aim on one knob, see the TDK-2307 side-mirror adjustment module; the commercial vehicle mirror systems buyer guide covers how powered mirror control works and where camera monitor systems (electronic mirrors) fit as regulations open up. To request the connector pinout, the panel cut-out, the key legend set or a fleet-grade batch quotation, please use the contact page with your target vehicle programme, expected annual volume, and key requirements (12 V or 24 V system, mirror-heat channel, legend language, connector preference). Drawings welcome.
