Selling for parts only since we replaced the television in the 90\'s and can\'t confirm the remotes work (they still worked on the old television, which is why we kept them).
We have two models of the Zenith Space Commander, a Model 400 and a Model 600. All the buttons click except for the Channel Lower button on the 600 model, which also remains depressed when pushed.
We\'ll ship these for $4.50 and we combine shipping, with the savings going to the buyer.
From Time Magazine:
Zenith Space CommandBy Peter HaMonday, October 25, 2010.Sounds more like a science-fiction novel than a wireless remote control for your TV, right? Developed by Robert Adler in 1956, the Space Command replaced the wired Lazy Bones controller that had been introduced by Zenith in 1950. Unlike today\'s battery-powered remotes, the Space Command was purely mechanical: pushing a button caused a tiny hammer inside the control to hit an aluminum rod that produced an ultrasonic sound. The TV interpreted the various clicks as commands to turn the TV on or off, mute the sound, turn the volume up or down or change the channel. There was enough noise from pressing each button that folks began calling the controller a \"clicker.\"
