Frequently Asked Questions
What type of switching circuit does each position control?
Each of the four positions is an independent single-pole, single-throw (SPST) switch. Sliding an actuator to the ON position closes that individual circuit.
Will this switch fit a standard 8-pin IC socket or breadboard?
Yes. The pins use standard 0.100-inch (2.54 mm) dual inline spacing, designed to plug into standard 8-pin DIP sockets or solder directly onto standard through-hole circuit boards.
Four crisp white slides and a blue body from the golden age of breadboarding. Set your logic, plug it into the socket, and let the circuit run.
