DESIGN FEATURES
High quality, field-proven Switchcraft
in a wide selection of illuminated and non-illuminated versions,
2- and 3-position, locking and non-locking functions can be
provided. Switchcraft illuminated lever switches feature choice of
colors, wide selection of switching circuits, single lamp
illumination and ease of mounting and lamp replacement.
All switches utilize nickel silver springs without “form” at point
of flexing to insure long spring life. The springs are assembled
into a conventional stack assembly, insulated from each other
by phenolic spacers with plastic tubing press-fit through each
stack, insuring correct alignment of contacts and providing
high insulation resistance.
APPLICATIONS
Various front panel switching applications on computers,
telecommunications systems, industrial control equipment,
intercoms, ground support systems, medical electronics,
scientific
instrumentation.
CONTACTS
Below are listed the basic contacts available on switches in
this catalog:
1. Fine silver contacts rated at 2A, 200W (maximum)
2. Welded cross bar silver contacts rated at 3A,
3. Welded cross bar palladium contacts rated at 2A,
4. Welded cross bar gold alloy contacts rated at up to 1A,
BASIC CONTACT FORMS
Below are the basic contact forms available standard on all
Switchcraft Lever Switches. Specify circuits needed by
referring to the letter identification and respective location on
frame. See dimensional drawings for stack switch location.
AC non-inductive load.
300W (maximum) AC non-inductive load.
200W (maximum) AC non-inductive load.

To avoid ordering special switches it is possible to use a larger
standard circuit, providing the circuit fulfills your requirements.
Circuit Form K is widely used in talk-listen (intercom) function
applications. In normal position (neutral), switch does not
contact upper or lower contact spring. During typical
operation, lever is held in upper (momentary) position while
speaking. Releasing lever allows switch to return to neutral.
For listening, lever is moved to down (locking) position. Lever
is manually returned to neutral when finished.
ORDERING STANDARD SWITCHES
Order lever switches by part number from pages 295
through 298.
LAMP DATA
Lever-Lite
are available from commercial sources.
ORDERING SPECIAL SWITCHES
Lever Switches
Should you desire a special version of any Switchcraft
switch not shown here, we require the following information:
1. Switch series.
2. Number of positions.
3. Mechanical action (locking, non-locking, etc.).
4. Contact configuration for each position.
5. Type of contact material.
6. Color sequence (Lever-Lite III).
UL RECOGNIZED LEVER SWITCHES
