GENERAL PURPOSE STACK SWITCHES
MINIATURE .188" (4.78MM) STACK SWITCHES
GENERAL PURPOSE STACK SWITCHES
(SPECIAL ORDER ONLY)
Complete general purpose stack switch assemblies are
made from a pile-up of various actuator springs, contact
springs and lifters. These stack switch assemblies can be
used on manually operated control devices where switching
is operated by cams, push-buttons and other similar
mechanical devices. The stack switch assembly is made up
of an actuator spring and various contact springs. These
current carrying members are insulated from each other by
phenolic spacers with plastic tubing press fitted through the
stack; thereby insuring correct alignment of contacts and
providing high insulation resistance when mounted.
Many Tini-Stack
Switch mounting centers are .188" (4.78 mm) (minimum).
Practical spring length is 1.750" (44.45 mm) (maximum).
SPECIFICATIONS
Springs: Copper alloy, in most standard gauge thickness-
es ranging from .006" (0.15 mm) to .016" (0.41 mm).
Spacers: Rigid plastic, available in thickness of .015"
(0.38 mm), .032" (0.81 mm) and .046" (1.17 mm).
Contacts: Welded cross bar palladium rated at 2A, 200W
AC non-inductive load. Gold alloy generally recommended
for “dry” circuit applications.
Tubing: Thermoplastic.
Lifters: Thermoplastic.
Mounting Hardware: Pressure plate, twin nut and screws:
Steel, plated.
.375" STACK SWITCHES
Thousands of switching combinations are possible. Switch
mounting centers are .375" (9.52 mm) (minimum) with
.25" (6.35 mm) wide switch parts. Practical spring length
is 2.625" (66.68 mm) (maximum). Contact Switchcraft for
selection of contacts and ratings.
®
switching combinations are possible.
DIMENSIONS ARE FOR REFERENCE ONLY
The types of General Purpose Stack Switch Components
available are:
• .375" (9.52 mm) mounting centers
• .250" (6.35 mm) mounting centers
• “Tini-Stack” Switches .188" (4.78 mm) mounting centers
• Telephone Relay Type Switches .250" (6.25 mm) mounting
STACK SWITCH COMPONENTS
Switchcraft offers various stack switch components, such as
contact springs, spacers, lifters, etc., in many lengths, thicknesses,
mounting centers and other details.
Switchcraft can assemble components into innumerable different
stack switch assemblies. It is impossible to catalog every type of
stack that has been manufactured. Stack switch assemblies can be
designed to meet UL requirements, but only as part of equipment.
TELEPHONE RELAY TYPE SWITCHES
Compact stack switches are particularly suitable for low activating
force, such as in relay and magnetic operated devices.
Contact Switchcraft for selection of contacts and ratings.
SPECIFICATIONS
Springs: Copper alloy, in thicknesses ranging from
.006" (0.15 mm) to .012" (0.30 mm).
Spacers: Rigid plastic is standard in thickness of .031"
(.79 mm), .047" (1.19 mm) and .063" (1.60 mm).
Contacts: Fine silver or welded cross bar palladium
are standard. Palladium or gold alloy are generally
recommended for “dry” circuit applications. Other contacts
available for varied customer requirements on special order.
Tubing: Thermoplastic.
Lifters: Thermoplastic.
Bracket: Steel, plated.
Mounting Hardware: Pressure plate, twin nut and screws:
Steel, plated.
.250" (6.35 MM) STACK SWITCHES
Thousands of switching combinations are possible with slightly
smaller parts. Mounting centers are .250" (6.35 mm) (minimum)
with .188" (4.78 mm) wide parts. Practical spring length
is 2.125" (53.98 mm) (maximum). Contact Switchcraft for
selection of contacts and ratings.
