A slide switch works by sliding a slight lever or actuator from side to side, opening and closing an electrical circuit. The actuator has a set of contacts moving inside the switch, which come together to complete a circuit or move apart to break the connection.
SPTD Switch
The pin in the middle is fixed. When the handle is pushed to the left, the two pins on the left are connected, and when it is pushed to the right, the two pins on the right are connected, thus switching the circuit.
Applications of Slide Switches
Consumer Electronics: Think remote controls, toys, and small gadgets.
Industrial Equipment: Often used in machinery for mode selection or emergency stops.
Automotive: Used in dashboard controls and other vehicle systems.
Home Appliances: These are common in items like coffee makers, fans, and heaters.
How to Select the Right Slide Switch?
Step 1 Slide Switch Function: First, know exactly what you want the slide switch to accomplish. Do you use it for device on and off, mode selection, or something else?
Step 2 Electrical Specifications: Ensure the slide switch rating is suitable for handling the current and voltage requirements of the application.
Step 3 Environment: Will it be used in a dusty, wet, or harsh environment? If so, look for protection-rated switches, such as IP-rated ones.
Step 4 Mounting Method: Determine how you’ll mount the switch, whether it’s through-hole, surface mount, or panel mount.
Step 5 Termination Style: Selection of termination style used to connect the device to a system, such as PC pins, screw terminals, or wire leads.

These switches work as expected. They click into place when switching so that the position stays set. These fit the breadboards I had lying around with no issues. This set comes in a convenient case to keep these switches handy for your projects.

Well packaged, convenient and consistent switches. Can't ask more from a commodity component.

These slide switches are ideal for replacing jumpers on circuit board designs to add options in circuits. Pin spacing fits standard 2.5mm hole spacing commonly used in proto boards and Dupont connectors. The leads are long and stiff enough that the switch can be elevated slightly above the board to clear other component for easy finger manipulation. Switch action has a good positive feel to it and looks to be of solid construction.

I got these for many types of projects—Arduino, home automation, teaching electronics to youth groups, etc. They are pretty standard SPDT switches. They are small enough for limited space projects, seem robust enough, and very inexpensive. They also fit well in my breadboards, which was not true of some other switches I’ve gotten recently. With 120 of them I probably will never need to buy more, but I would get these again if I needed them.

Good through-hole power switches for DIY circuit board projects. The 20-30 quantity variant on this listing is larger switches with fairly large leads (they have to be for the 10A rated current), and will not fit on breadboards. They switch with a nice "click" and are not mushy.

Great pack of switches. Building a control panel and need lots of switches on it. This pack is perfect. Easy to solder to and attach to panels. Very good value.

As I continue to build my own projects but also as I continue to repair devices for family and friends I find myself in need of components like switches and even active devices that will fit in tiny housings. Recently I repaired a Bluetooth Page-turner pedal for my wife. The on-off switch failed and thus started my search for a replacement. These are not an exact replacement given that the PCB switch that failed had 6 legs and was even smaller. This switch however fit perfectly in another position in the case where I drilled a hole and mounted it carefully with glue. Overall I am delighted to have a lifetime supply of tiny slider switches for a good price. Random tests of a number of these switches showed correct operation and apparent quality.Packaging is a handy reusable plastic box.

Given that this product claims to be for breadboards, not ALL breadboards are compatible. The pins are a bit large for one of two solderless breadboards, and for one of one traditional solder-style breadboards. If this is your intended use case, perhaps you should look elsewhere.As per my calipers, the dimensions of the pins are accurately given - 1.27mm by 0.27mm. The 1.27mm is a bit too large for the standard 1.067mm breadboard holes. This is something I should have checked - but saying it works with breadboards is a bit disingenuous.
