Your standard, basic, everyday, found-on-every-wall SPST toggle switch in dark brown. It's from G.E., with the standard 3-3/8" center-to-center spacing on the mounting flanges. Rated for up to 15A at 120V. UL.

It's special. Our 4-1/2" x 2-3/4" white-plastic switch plate has a generous 2-5/8" x 1-5/16" center cutout and fits a wide, push-type rocker switch rather than a standard toggle. Includes mounting screws.

We thought power corrupts, but it turns out otherwise. Power locks. You could put these in a car door, or think up something really kinetically clever. These brand new 12VDC door lock actuator assemblies draw 2.6A pushing or pulling with a 5/8" throw. Measures 6-3/8" overall, 3-3/4" from the tip to the right-angle gear motor, which extends 1-5/16" out from the 1-3/16" thick body. Top has a removable plastic ring, the shaft is covered by a rubber boot and the bottom has 7-1/2" leads with bullet connectors. Comes with an eight-hole 8-7/8" x 9/16" steel mounting bracket, a 8-3/4" rod and assorted screws and mounting hardware.

This 3-way, 120VAC refrigeration valve from Ranco has (3) 6" copper tubes on the valve stem controlled by solenoid action, which opens and closes ports to each tube. Measures 4" long including solenoid and valve x 1-1/4" x 1-1/2". Could be part of a cooler or vending system. Ranco part # 1122030-1071.

It's special. Our 4-1/2" x 2-3/4" white-plastic switch plate has a generous 2-5/8" x 1-5/16" center cutout and fits a wide, push-type rocker switch rather than a standard toggle. Includes mounting screws.

This little solenoid air valve requires 220mA at 24VDC and is normally closed. Working pressure is 6 psi. The inlet and outlet are 3/16" OD x 3/32" ID x 1/4" long at right angles to each other. Comes with 6" leads with a Molex connector. Part #AJK-F0507.

Our latest normally closed solenoid valve from Parker fluid control division draws 6W at 110VAC and is rated for up to 10psi. Measures 2-3/16" x 1-7/8" x 2-1/8" counting the right-angle 1/4” dia brass hose barb ports on the left and the right-angle 3/16” brass hose barb port on the right. Includes a 1-3/4” L-bracket for mounting. Has a pair of 1/4” quick-disconnect terminals for power. UL/CSA. Mfg’s part # 15-200470-001 "B".

This 24VAC 6VA electro-pneumatic valve from Siemens USA, #265-1027, has three barbed plastic tube connections- normally open, normally closed and a common for 1/4" OD tubing and is rated for a max of 50psi. Commonly used to alternately apply pressure to and exhaust pressure from pneumatically controlled devices, but we're sure you'll find a clever way to use them in your weekend project. Measures just over 2" x 1-1/2" x 1" and is mounted on a 2-7/8" x 3/4" bracket with 3/16" mounting holes and 9" leads. UL.

From Broan-NuTone®, these rocker switches are rated for up to 15A per switch, 20A altogether. Fit standard, single-gang electrical boxes and come with switch plates, screws and wiring instructions. You pick dual or triple switches. You’ll need a grounded box. UL.

We find ourselves in possession of a bunch of 10- microsolenoid switches from the Lee Company. They’re rated for 12VDC and 5 psid, probably between 250-500mA, mounted in a 2-1/2” x 2” x 7/8” metal block with a 1/16” inlet barb. Yours might come with one or more breakout cables and/or a 3-5/8” x 2-5/8” x 1-3/4” offset block. We believe the solenoids (Lee part # LHDX0515700BB) are epoxied onto the blocks.

Black plastic momentary push-button switch. Rated 1/4 amp at 250 VAC. Measures 1-3/8” tall, fits 3/8” hole. Panel-mount, with a pair of nuts on the threaded shaft, and (2) screw terminals. Great for all of your DIYers, makers and hobbyists of all stripes.

Perfect for night toggling. This panel-mount SPST toggle switch is rated for 12V up to 16A and has a green indicator lamp that will draw 300mA. Housing is just shy of 1" x 1/2" square with a 1” bat and (3) quick-disconnect terminals. Includes a plastic nut and washer, and is made in Singapore, where it’s illegal to chew gum. (We’re just saying.)

Were you the one who needed an industrial relay? Oh, great, because here’s one from Midtex, and it’s rated for 30A and 1HP at 120VAC; 30A and 1.5HP at 240VAC; and 15A at 600VAC. Has SPST normally-closed load contacts, and coil will draw 25mA at 12VDC. Measures 2" x 1-3/4" x 2-3/8", including a plastic bracket on the face. Has 1/4" quick-disconnect terminals on the bottom.

We relay like this Schneider Electric solid-state relay, which is rated at 32VDC with a 24-280VAC 10A load. This little device has lots of nice features, including an optically coupled circuit to provide isolation between input and output, an internal snubber to protect from high voltage transients, and an internal heat sink for thermal management. All in a slim package with no mechanical parts, for longer reliability and silent operation. Operating temps are -30C to +80C. CIP rating: IP20, Series 861. Relay Contact Form: 1 Form A (SPST-NO) Output. Type: SCR Control Voltage Range. Part No: 861SSR210-DC-1

This is what we would call a very nice solenoid valve, from Deltrol Fluid Products. Draws 1A at 12VDC, has an operating pressure of 0-12" water column, can handle liquid to 99 degrees Celsius, and is rated for continuous duty. Measures 4-1/4" x 3" x 1-7/8". Inlet and outlet are both 9/16" outer-dimension, and has 5/16" inner-dimension mounting wings on both sides, plus 2-1/2" leads with a 5mm Molex connector. Part #DSVP11N Made in USA.
