About the Plus Minus Diagonal Button black outline icon
A rounded rectangle frame holds a long diagonal stroke that runs corner to corner, with a plus sign in the upper left space and a minus sign in the lower right. It is the standard shorthand for stepping a value up or down, so it suits camera exposure controls, contrast and brightness sliders, zoom keys, quantity steppers and calculator or spreadsheet toolbars.
The diagonal divides the key into two equal triangles, keeping plus and minus balanced and far enough apart to stay distinct. It sits comfortably next to zoom, brightness and settings keys in a control strip. Keep the stroke weight equal on all three marks so neither sign dominates.
This is the black outline version of the plus minus diagonal button icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
