GENERAL PURPOSE STACK SWITCHES – COMPONENT SPECIFICATIONS
STACK SWITCH COMPONENT SPECIFICATIONS
1. SPRINGS - Copper alloy in most standard gauge thickness-
es of .006" (0.15 mm), .008" (0.20 mm), .010" (0.25 mm), .012"
(0.30 mm), .016" (0.40 mm) and .020" (0.50 mm), a few designs
can be made up to .031" (.079 mm) thick. All or any contact
point hole can be provided; spring can be cut at any point.
2. BRACKETS - Standard brackets are detailed on drawing.
Tools are flexible so that various lengths from same width
stock can be provided.
3. LIFTERS OR PUSHERS - .125" (3.18 mm) and .188" (4.78
mm) diameter thermoplastic in various lengths staked into
one of the contact point holds provides tandem action
between blades or to serve as an actuator.
4. MOUNTING HARDWARE - Pressure plates (S1293 and
S2300) twin nuts (S1008 and S1431) and screws available for
mounting.
5. LEAF INSULATORS - Punched in same shape as springs
in .015" (0.38 mm) thickness of fish paper or mylar.
6. SPACERS - Rigid plastic is standard in thicknesses of .015"
(0.38 mm), .032" (0.81 mm), .051" (1.30 mm) and .062" (1.57
mm). Thickness of .093" (2.36 mm) is available for .375" (9.52
mm) mounting centers only. For longer surface creepage
paths, use both large and standard sized spacers. High tem-
perature insulation also available.
7. THERMOPLASTIC TUBING - .375" (9.52 mm) mounting
centers pass #5 screw. .250" (6.35 mm) mounting centers pass
#3 screw. .188" (4.78 mm) mounting centers pass #2 screw.
8. CAM FOLLOWERS - Two roller bracket designs (G1734
and G2298) available for springs .250" (6.35 mm) wide.
Copper alloy standard. Can be furnished in various diameters
and materials. Thermoplastic rollers also available.
9. CONTACTS - Welded cross bar contacts are commonly
used for cost savings. However, riveted contacts are available.
Size and material depend on circuit requirements (supply
complete details). For low level audio circuits, we suggest gold
alloy or palladium cross bar contacts. Springs can be
bifurcated (two contacts per spring).
