These black aluminum alloy heat sinks have flared fins at 1-3/8" x 1-1/2" x 1/2" with (2) pins out one short side and (3) 1/8" mounting holes in the center. Wethinks these are PCB mounts for TO series chips.

We believe this is a replacement switch activated by closing the door of a microwave. It’s a N/O (normally open) microswitch from Dongnan Electronics, rated for 5A at 125V and 2A at 250V. Comes with a bent 1-3/4” lever and is prewired with 19” leads and a 2-pin 5.5mm Molex connector. UL.

This gray plastic gear is 1-13/16" dia x 3/32" with (56) teeth, 32-pitch, and a 14-1/2° pressure angle with a 3/8" long x 19/32" OD x 3/8" ID bore ready for a keyed shaft. Has (2) 1/4" bores on the face.

Our 4-1/2" long x 2" wide x 1" deep cell phones fit nicely in this black-leather carrying case. The front is a 2-1/2" x 1-5/8" window of clear plastic through which you can press the buttons. The case is open on the bottom so you can access the ports, and comes with a 6" wrist strap and a plastic belt/pocket clip. A small strap snaps over the phone antenna to keep it from slipping out. Unfortunately, if your phone doesn't have an external antenna, there is nothing to keep it in except a snug fit, an extraordinarily rigid posture, and a determination to never bend over.

These single-digit displays with (8) LED segments in a DIP draws approx 150mA between 1.5 and 2.5 VDC. This is numeric because some segments' pins are internally shorted. Common cathode ground. Yellow segments. Measures 28mm x 17.5mm with 13 pins.

Little black plastic gear, 1-1/32" dia x 3/32" thick with (34) teeth, 32-pitch with a 14-1/2 degree pressure angle and a 3/8" long, 11/32" 9-tooth shaft, same pitch, with the teeth on the outer half. Has (3) equidistant 3/16" bores in the face, and a 5/32" bore on the shaft side, 3/32" on the face side.

The mightiest mites of all, piezo elements. These are mounted in a 9/16" dia x 1/4" thick housing with a pair of 3/16" radial leads. The positive lead is marked.

This thermal fuse has 1.6 ohm resistance at the terminals, so at 6V should handle up to 3.75A. Housing measures 1-1/4" x 3/4" x 5/8" with a pair of  3/16" terminals on the bottom. Normally closed. Made in the USA in the early '90s for use in a Power Wheels® battery in a Super 6™ Volt Vehicle models 85000-85999, PP940 AND PP941.

With this 1.2K OHM 10% tolerance power resistor. Rated 3 to 5 watts, it has a ceramic block body 3/8" sq x 1-1/2" long with wire leads on ends, one of which is 1/2" long and the other 1-1/2". Any questions?

These black-plastic brackets with (2) 1/8” mounting holes are designed to hold the IEC jack on a computer. The bracket for a flush mount has locking tabs, inside dimensions of 1–3/32” x 13/16” plus side slots, and will stand 1/8” off the panel. The bracket for a recessed mount has locking tabs, inside dimensions of 1–1/16” x 3/4” plus side slots, and a 3/16” deep well. The swivel bracket is 2” x 1–1/16” x 1–1/2” OA and includes a strain relief that can swivel 180°.

Is it spring? Well, it’s a spring. This steel extension spring is technically a “short throttle return spring” and measures 2-1/4" long x 7/16", but it will be just as happy returning anything else if your throttle is already back where it belongs.

Our black anodized channel-style heat sink measures 1-1/4" x 1-1/2" x 7/16" with folded back fins and a pair of 1/8" mounting holes in the flat center. Come on, you've got some heat to sink. Who doesn't?

These 15uH chokes are encased in clear heat-shrink tubing with pre-soldered jumper leads. Rated for up to 4A and measure approx 4-1/2" long. Made in Germany.

Time was, these were sticking through the trunk of every 1984 Taurus on the planet. Now the car phone is mostly a memory, but you can own the antennas for a song. These are passive, 13" long with the bottom 2-1/2" in a coil and a ferrite choke halfway up. Base has a 5/32" - 24 thread.

This black aluminum heat sink measures 4" x 2" x 1-1/14" with a 2" x 2-1/4" base. (6) 5/16" thick fins at the top and a set of (5) more at the bottom above the base. In between the fins is a 1-1/4" x 2" space for your chip with a 1-1/8" square thermal pad and a 3/16" bore.

It's a nonpolarized bimetal heat sensor, 1/2" long with rubber sleeves and 6" long leads. It's also mysterious, because when used as a thermocouple multimeter input, it reads approx 94° in nearly boiling water but approx 170° in ambient air. Wethinks some sort of inversion or scaling is going on, but a person with your smarts will surely figure it out.

These vacuum-sealed glass-cylinder switches have bimetal contacts inside. Normally open, they make contact at approx 500°F. Our vacuum-sealed-bimetal-switch boffin calls the leads "pretty skinny" and suggests low-power applications only. Measure 1-1/8" x 1/2" dia with 3/4" long leads.

You'll suffer keyboard boredom no more when you have this set of stickers to slap onto the keys of any standard-size ASCII keyboard. Also good for anyone who has worn the letters off of their keys. Exciting designs include a Holstein cow pattern, OD camo, tropical fish and raindrops for that popular wet look. You'll get (2) different sets, including a few spare stickers for over-sized keys. Made in Israel.
