Yes, it sounds like you have a toggle solenoid similar to the one I used. You won't need to change this to reduce the on current, it is momentary. A solenoid is a open or close path, like a wall light switch. Some maintain the pass thru position by pulling a spring contact closed with power that produces a magnetic field to hold the contact closed ( or open depending on the design and requirement). If you remove the power then the, spring retracts the contact a n d the path is broken, hence the term disconnect switch. The fail/safe powered state is normally open or no path. A relay can be exactly the same but usually is much lower current because it it has contacts like the points in a old car distributor ( old... as in pre 1970). Relays often have multiple paths and contacts. Solenoids can conduct 300 - 500 amps thru the large contacts or more, whereas relays are typically under 30 amps.
