#100059 - Relay
Responding to: Russell Bull's previous message
Note also that relays inherently provide both galvanic isolation for the control electronics, and give a full disconnect when OFF.

The load is not fully isolated when the triac is OFF - so you might have to add additional isolation anyway.

Also, beware of funny effects with triacs due to inductive loads, and possible some other "electronic" loads.
(there was a post here a while back about problems with triac switching for fluourescent lamps with electronic ballasts...)
