How to Choose the Right Deca Product

Confirm the Function

Choose the product for your application (DIN-Rail terminal block or control switch). Take note of shutdown, push-button input, mode selection, wiring, grounding, or circuit-disconnect functionality.

Check the Ratings

Match specs such as voltage, current, wire gauge, contact arrangement, or illumination voltage to the circuit.

Verify the Operation

When choosing a control switch, select momentary, maintained, push-lock, twist-release, or spring-return operation.

Confirm Panel Fit

For control switches, verify the 22mm panel opening, available mounting depth, DIN rail space, and wiring clearance.
