However you can use a standard DPDT (ON) OFF (ON) momentary switch to get what you want, or close to it anyway. This will work IF you can live with the center position as OFF and then use the (left and right) positions as onA and both onA and onB. A DPDT switch is two SPDT switches in the same package. So lets call them switches A and B.

2010年8月17日 · What are the simplest, cheapest, smallest ways to make a momentary switch produce a 2-state toggling output (latching momentary switch)? In other words, the output is continuously low, and when you momentarily press the button/tact switch, the output changes to continuously high, and then when you press it again, it switches back to low.

"Momentary" means that they're only on while you're pushing them like a key on your keyboard, rather than latching, which means that they stay where you put them like a light switch. This might be a spring-loaded toggle switch, or they might be a pushbutton. It may also be a pair of switches or contactors sharing a single activation lever.

2024年12月9日 · (EDIT: Click the image to enlarge it.) This circuit works on a 0V-9V supply (with 4.5V as the VREF). The momentary switches being used are Normally Open (making contact between the leads when the buttons are pressed). For the sake of clarity I have omitted the associated components with channels A and B.

2017年12月8日 · You may have a difficult time finding a 4P2T switch or button that is momentary though. Another thing to look out for would be to ensure the switch is a "make before break" style switch, which means the pins are all briefly disconnected from each other while in …

2021年5月6日 · The difference between AC and DC switches is the contact rating inside. AC voltage basically goes up and down past zero, so if there are any electrical arcs they extinguish themselves when the voltage crosses zero. DC stays constant, so …

2019年8月14日 · \$\begingroup\$ @MarcBrillault The reed switches come with different selectable responses to magnet strength. With a smaller range of action, I believe it's still "doable." But you may need to correctly match the magnet with the reed switch to succeed. So it would take some careful thought to select a few reed switches in the right ballpark.

2021年11月7日 · Motor is 6-8 amps, switches are rated for 18 amps. S1 is a latching push button switch which is currently working fine. S2 and S3 are momentary. I'm having trouble translating diagrams to actual wiring and components. One bit that is causing me some confusion is the types of switches I'm using for this project.

2013年5月25日 · One suggestion is to get an Omron B3F-6000 series (I ordered the Omron B3F-6022, Mouser has 'em) or equivalent switch instead of the four-legged types you are currently using. As the drawing below indicates -- these switches have two pins, on a 5mm spacing, which makes them almost ideal for breadboarding.

The mechanism actuating the transition between these two states (open or closed) can be either a "toggle" (flip switch for continuous "on" or "off") or "momentary" (push-for "on" or push-for "off") type. But a quick websearch seems to show that there are some switches sold as momentary toggles, so I'm not sure there is a completely unambiguous ...
