Push The Button

These pushbutton switches have (8) sets of SPDT contacts and measure 2-3/8" long (not counting the button) x 1" x 5/8". The contacts for both rows, starting at the pushbutton, are normally closed; common; and normally open with (4) sets in each row. When the pushbutton is engaged, the window at the front is green. We think these were used as buss switches. Made in the USA for ITT/Schadow.

DISKETTE CASES

Individual cases for 3–1/2” computer discs. The nice thing about these is that they are stiff enough to protect the disc but just flexible enough not to be brittle and break the way most “jewel” cases do. Red, blue, purple or gold, all are translucent enough to read interior labels. We pick your color.

Ten Roentgens & Counting…

If Madame Curie had owned this, she'd be alive today. (She'd be more than 140 years old, of course, but still….) Our Radex RD1503 digital radiation meter evaluates the ambient level of gamma radiation, and can detect objects polluted by beta active radioactive nuclides. It uses a Geiger counter to detect the amount of gamma radiation within 40 seconds. It indicates the ambient dose equivalent in µSv/hr (0.05 to 9.99) and the µRem/hr exposure dose rate on a scale of 0.1 to1.25. The values are displayed on a 1-3/4" x 1-1/8" LCD screen. The presence of each particle is indicated by a clicking sound, for quick identification of affected areas, and it has an audio alarm with 3 adjustable ranges. The unit measures 4" x 2-1/4" x 1" and comes with a detailed manual and technical certificate. Requires (2) "AAA" batteries. Made in Russia. CE.

No Mount Motor

Our motorman, CJ, called this reversible 12-24VDC motor strange, mostly because it has the power contacts mounted on the face, bracketing the 11/16" x 1/8" mostly striated shaft, and has no mounting brackets. But that shouldn't stop a clever person like you. (Hint: it was probably made to fit into a sleeve of some sort.) At 12VDC, draws 100mA no load, stalls 850mA and spins approx 900 rpm; at 24VDC, draws 150mA, stalls 2.2A and spins approx 1800 rpm.  Measures 2-1/4" x 1-13/32" dia.
