The engineering question

Which switching function must be safe, repeatable and verifiable under the real operating conditions?

Build the component brief before choosing a model

A credible design-in request defines the electrical duty, environment, protection strategy and qualification plan. Product choice comes after the system boundary is clear.

Define

Map normal operation, abnormal operation and the safe state.

Calculate

Capture voltage, current, inrush, fault energy, temperature and duty.

Shortlist

Choose a product family and example ordering-code candidates.

Validate

Review official evidence, sample, test and approve in the application.
