Junk drawer star -[ HMM ]-

Another view of a relay I photographed earlier this year for a February Alphabet Fun Month submission. After that photoshoot, I returned it to the junk drawer I originally found it in; I pulled it out for this assignment unaware I had used it earlier, so I guess this shot , as it turns out, is this old-school relay's encore.

 

This is a latching relay. Unlike a regular relay which switches only while the coil is powered, this one uses a mechanism to alternate between two contact states when the coil is pulsed.
