Gap:

The shortest straight-line distance between two separate contacts.

Inrush:

The initial transitory high-level of current at contact closing (making). A characteristic of capacitive and some resistive loads. The inrush currents can be large and long enough to cause severe degradation of the contacts. See Resistive Load. Capacitive Load. Power...

EMC:

Electro-Magnetic Compatibility.

Gated:

Restricted movement in XY axis only.

High Inrush:

A brief pulse of very high electrical current, much greater than the design load, that occurs when the electrical load is initially applied to the circuit.
